(A) Lorraine is not opposed to being paid less than Pauline.
Wrong. It does not matter whether Lorraine is opposed or not, since company will be the one paying. Out of Scope.
(B) The company's pay scale is intended to compensate more difficult work with higher wages.
Correct. If company pay scale is intended to compensate more difficult work with higher wages, then Pauline should be paid more than Lorraine as Pauline is doing more difficult work than her.
(C) Pauline expects to be promoted to a higher paying position.
Wrong.We are not concerned with any promotion in position, Pauline can be paid higher wages even without promotion.
(D) Lorraine was paid more than either woman expected Lorraine to be paid.
Wrong. Totally out of scope. The option does not even tell whether Lorraine did more difficult work than others or not.
(E) Pauline has fewer years of experience in her current job than Lorraine has in hers.
Wrong. If at all this option does something, it weakens Pauline's claim to be paid more than Lorraine, because Pauline is less experienced than Lorraine.
I hope this helps:)
