Correct option is A
Article 51(A) of the Constitution lists the Fundamental Duties of Indian citizens. The idea of Fundamental Duties was borrowed from the Constitution of the Soviet Union and was added by the 42nd Amendment Act, 1976.
Fundamental Duties include:
To uphold and protect the sovereignty, unity, and integrity of India.
To value and preserve the rich heritage of India’s composite culture.
To develop the scientific temper, humanism, and the spirit of inquiry and reform.
However, voting in general elections is not a Fundamental Duty under Article 51(A). Voting is a right, not a constitutional duty. Citizens are encouraged to vote, but it is not mandatory as a duty under the Constitution.
