The correct option is B Gives official status to one religion
Indian constitution does not give official status to one religion. It is a Secular Nation. Secularism in India means equal treatment of all religions by the state. With the 42nd Amendment of the Constitution of India enacted in 1976, the Preamble to the Constitution asserted that India is a secular nation. However, neither India's constitution nor its laws define the relationship between religion and state. The laws implicitly require the state and its institutions to recognize and accept all religions, enforce parliamentary laws instead of religious laws, and respect pluralism.
