Option (C) is correct. Communal politics is based on the idea that religion is the principal basis of the social community. It operates on the belief that followers of a particular religion constitute one community (Statement C) and involves the belief in the superiority of one religion over others (Statement A).

Statements B and D are incorrect descriptions of communal politics. Communalism leads to the belief that people belonging to different religions cannot live as equal citizens within one nation. Furthermore, communal politics involves using state power to establish the domination of one religious group over the rest, rather than preventing it.
