(d) As per the Constitution, religion can never be separated from politics.
This statement is not true. The Indian Constitution upholds secularism, which means the state does not favour any religion and keeps religion separate from politics.
Options (a), (b), and (c) are all correct provisions of the Indian Constitution regarding secularism and religious freedom. Option (d) is false because India is a secular state — the Constitution actually ensures separation of religion from state/politics. Examiners expect students to directly identify the incorrect option and briefly justify why it is wrong.
