• Article 25 of the Indian Constitution guarantees freedom of conscience and free profession, practice, and propagation of religion. This allows individuals to follow, practice, and propagate their faith.

• Right to wear and carry ‘Kripans’ by Sikhs is considered a part of the right to freedom of religion, as per Explanation-I of Article 25, which protects the practice of Sikhs carrying 'Kripans' as a religious symbol.

• The State’s right to make laws for social reforms is also included under the right to freedom of religion. This allows the state to regulate religious practices for social welfare and reform.

• However, the right to conversion of religion by religious bodies is not included under Article 25. The constitution does not provide any right for religious bodies to forcefully convert individuals to another religion.

Thus, the correct answer is (a), as it includes freedom of propagation of religion, the right to carry 'Kripans', and the State’s right to make laws for social reforms.
