The correct answer is (d) Parliament.
The Constitution of India, Article 11, states that “Parliament may make provision for the acquisition of citizenship of India by naturalization or registration.” This means that Parliament has the sole authority to decide who can become a citizen of India.
The Election Commission is an independent body that is responsible for conducting elections in India. It does not have any authority to make laws or to prescribe conditions for the acquisition of citizenship.
The President is the head of state of India. He or she has the power to sign laws into effect, but does not have the power to make laws on his or her own.
The State Legislatures are the legislative bodies of the states of India. They have the power to make laws on matters that are not specifically mentioned in the Constitution as being within the exclusive domain of Parliament. However, the Constitution does not give the State Legislatures the power to make laws on matters related to citizenship.
Therefore, the only body that is competent to prescribe conditions for the acquisition of citizenship is Parliament.
