Answer: D

Explanation:

Statement 1 is correct: Developed by the Research Centre Imarat (RCI) and the Indian Air Force (IAF), the RudraM-II is an indigenous next-generation air-to-surface Anti-Radiation Missile (ARM). Its primary role is to detect and neutralize enemy air defense systems, including radar stations, surface-to-air missile (SAM) sites, and surveillance networks.

Statement 2 is correct: The missile employs a highly advanced, multi-layered guidance system. Aside from using a Passive Radar Homing (PRH) system to track radio frequency emissions, it is equipped with an Imaging Infrared (IIR) seeker. This allows the missile to hit its target with pinpoint accuracy even if the enemy engages the classic evasion tactic of shutting off their radar mid-flight.

Statement 3 is correct: Designed to provide stand-off capabilities, RudraM-II has an estimated operational range of 300–350 km and can achieve hypersonic speeds of up to Mach 5.5, significantly reducing enemy reaction time.

Answer: D

Explanation:

Statement 1: Correct. Mission "Senehjori" is a ₹411 crore cluster-based initiative jointly launched by the Ministry of Development of North Eastern Region (MDoNER) and the Government of Assam spanning from 2026 to 2028.

Statement 2: Correct. One of the central financial objectives of the mission is value addition, targeting an increase in the farm-gate returns for grassroots rearers and weavers from an historical average of ₹25,000 per kg to over ₹50,000 per kg.

Statement 3: Correct. To transform Muga silk into a globally competitive luxury brand, the mission introduces unified "Senehjori" branding along with digitally traceable, GI-linked systems for international consumer verification.

Answer: A

Explanation:

Statement 1: Correct. Sericulture in India differentiates between mulberry silk and wild silks. Muga, Eri, and Tasar are collectively classified under Vanya (wild) silks.

Statement 2: Correct. Muga silk is exclusively found in Assam and holds the distinction of being the world's only naturally golden silk, making it the first silk from India to receive GI protection status.

Statement 3: Incorrect. While Muga silk was historically used extensively in the royal attire of the Ahom dynasty and holds deep cultural value, it was never completely prohibited for the general population. Today, it remains a core element of traditional Assamese attire, such as the Mekhela Chador, and acts as a primary source of rural livelihood and women's empowerment.

Answer: A

Explanation:

Statement 1 is correct: The historical basis of the boundary between India and Nepal is rooted in the Treaty of Sugauli, which was signed in 1816 between the East India Company and the Kingdom of Nepal. It identified the Kali River as the western boundary of Nepal.

Statement 2 is correct: The primary structural friction involves differing cartographic interpretations. The treaty only defines the boundary along the river but fails to explicitly define the exact origin and major tributaries of the Mahakali.

Statement 3 is incorrect: The positions are reversed. Nepal argues that the Mahakali River originates from Limpiyadhura, which would place the disputed areas of Kalapani, Lipulekh, and Limpiyadhura on the Nepali side of the border. Conversely, India considers the source of the river to be closer to the Kalapani–Lipulekh region, viewing these areas as an integral part of the Pithoragarh district in Uttarakhand.

Answer: C

Explanation:

Statement 1 is correct: The legal framework strongly presumes legitimacy to protect family stability and the dignity of the child. This was earlier governed by Section 112 of the Indian Evidence Act, 1872 and is now covered under Section 116 of the Bharatiya Sakshya Adhiniyam (BSA), 2023. It states that a child born during a valid marriage, or within 280 days of its dissolution (with the mother remaining unmarried), is conclusively presumed to be legitimate, unless "non-access" between spouses is strictly proven.

Statement 2 is incorrect: The Supreme Court has repeatedly held that DNA tests are not to be ordered as a matter of routine or as a roving inquiry. In precedents like Goutam Kundu v. State of West Bengal (1993) and subsequent rulings, the Court established that a strong prima facie case must be made out before scientific testing is mandated. Mechanical or frivolous DNA testing would not only invade personal liberty and privacy but could also subject a child to unnecessary social stigma.

Statement 3 is correct: In Nandlal Wasudeo Badwaik v. Lata (2014), the Supreme Court cemented a two-stage principle. While the legal presumption governs under normal circumstances, when DNA tests are formally ordered and conducted, the resulting scientific truth can prevail over the legal presumption. The Court noted that when scientific evidence (like DNA) points entirely to a biological fact, legal presumptions cannot be used to suppress scientific reality.
