Explanation:

Statement 1 is correct: India and Malaysia elevated their diplomatic ties to a Comprehensive Strategic Partnership (CSP), which has been further reinforced through high-level bilateral summits and multiple framework agreements covering maritime security, defense tech, digital infrastructure, and semiconductor ecosystems.

Statement 2 is correct: Malaysia is a central pillar of India's Act East Policy and an essential partner in the Indo-Pacific architecture. Because roughly 60% of India's trade and energy supplies pass through the Strait of Malacca, cooperation with Malaysia is vital for freedom of navigation and regional maritime security.

Statement 2 is incorrect: The conference is organized annually by the Department of Official Language under the Ministry of Home Affairs (MHA), not the Ministry of Culture. It was initiated in 2021 and has previously traveled to cities like Varanasi, Surat, Pune, New Delhi, and Gandhinagar before heading to Maharashtra in 2026.

Statement 3 is correct: The Union Home Minister presented the Rajbhasha Gaurav and Rajbhasha Kirti Awards for the 2025–26 cycle to various ministries, public sector undertakings, banks, and individuals during the inaugural session.

Answer: B

Explanation:

Statement 1 is incorrect: Article 343(1) states that the official language of the Union shall be Hindi in the Devanagari script. It does not make Hindi the mandatory official language for all individual states. States have the constitutional freedom to adopt their own official language or languages under Article 345. Furthermore, India does not have a single designated "national language".

Statement 2 is incorrect: While Article 343 mandates Hindi in Devanagari script, it explicitly provides that the form of numerals for official Union purposes shall be the international form of Indian numerals (e.g., 1, 2, 3), not the Devanagari script numerals.

Statement 3 is correct: Article 343(2) provisioned that English would continue to be used for all official purposes of the Union for 15 years (until January 25, 1965) from the commencement of the Constitution. Later, Parliament enacted the Official Languages Act, 1963 to allow the continued use of English indefinitely.

Answer: A

Explanation:

Statement 1 is correct: In classical computing, a bit represents either a 0 or a 1. In quantum computing, fundamental units called qubits exploit quantum mechanics to use superposition, enabling them to represent 0, 1, or any quantum combination of both simultaneously.

Statement 2 is incorrect: Quantum decoherence is the loss of fragile quantum coherence. It happens when environmental interactions—such as thermal vibrations, radiation, or electromagnetic fields—disturb the quantum state, rather than strengthening it.

Statement 3 is incorrect: "Entanglement sudden death" describes a scenario where quantum entanglement disappears abruptly (suddenly) rather than fading away gradually.
