The correct option is A P R Q S
The constituent parts P, Q, R, S constitute different parts of a sentence, namely subject(P, R) and predicate(Q, S). P is an adjective which describes the main subject R, Q explains the action or doing verb and S denotes comparison . Since Q starts with a verb and a small letter, therefore it cannot be placed at the beginning of a sentence, hence Option A is wrong. The verb should come after the subject, not after the comparison, hence Option B is incorrect. Option C starts with the comparison part of the predicate and in small letters, hence it is also incorrect. Therefore Option D remains the correct option, that is "Indian working women earn as much as men."
