What is the most logical assumption that can be made from the passage given above ?

Correct Option: (d) Men do not understand their own religious denomination.

Passage 1 discusses the subjective nature of judging religious denominations. If everyone judges their own religion, none is wrong; if they judge others, none is right. The most logical assumption underlying this philosophical argument is that religious denominations tend to ignore the unity of man by creating divisive subjective judgments about right and wrong among different groups. Evaluating options: (a) is incorrect because the passage does not state that man cannot live without religion. (b) is incorrect as propagation is not discussed. (d) is incorrect as it goes beyond the text. Option (c) captures the essence that adherence to exclusive denominational judgments disregards universal human unity.
