“ do not jump into checking meaning logic before checking grammar because meaning logic is harder to realize than grammar error
I am sure this is typical question of gmat
check grammar
"after doing" need a previous clause not a preposition phrase "with...) because we need a subject in previous clause to be subject of doing. D and E are out. For example, --after failing many times on gmat, I win --
"had done ...after had don..." in B is wrong. there is no this pattern, no logic of tense sequence.
"it" in A can not refer to "profits"
C is left.
this is hard but by checking only grammar we can win soon.
