With respect to what are called denominations of religion, if everyone is left to be a judge of his own religion, there is no such things as religion that is wrong; but if they are to be a judge of each other’s religion, there is no such thing as a religion that is right, and therefore all the world is right or all the world is wrong in the matter of religion. What is the most logical assumption that can be made from the passage given above?

(a) Incorrect - The passage does not comment on the necessity of belonging to a religious denomination for survival. (b) Incorrect - There is no mention of a duty to spread one’s religious beliefs. (c) Correct - The assumption that "Religious denominations tend to overlook the unity of humanity" supports the central argument that judging others' religions can lead to all religions being seen as wrong. (d) Incorrect - The assumption should ideally be that people fail to understand others’ religious denominations, not necessarily their own.
