When religious identity overrides everything else, it leads to:

The correct answer is Option (3) → Communalism

Option (1) Secularism — Incorrect. Secularism, in the Indian sense, means that the state gives equal respect to all religions and does not favour any one of them. It keeps religion from dominating public life, so it is the opposite of letting religious identity override everything.

Option (2) Casteism — Incorrect. Casteism is loyalty to one’s own caste above all else, and the use of caste identity to gain advantage or to discriminate. Its basis is caste, not religion.

Option (3) Communalism — Correct. Communalism is aggressive chauvinism based on religious identity. One of its characteristic features is its claim that religious identity overrides everything else: whether one is rich or poor, whatever one’s occupation, caste or political beliefs, religion alone counts. It turns large and diverse groups into single, homogenous ones.

Option (4) Regionalism — Incorrect. Regionalism is loyalty to a region, rooted in the diversity of languages, cultures, tribes and religions concentrated in particular regions and fuelled by a sense of regional deprivation. Its focus is the region, not religion as such.
