You're right about (B), but there's an even more obvious reason to eliminate it.
This question is best approached by following the argument and then working wrong-to-right. The wrong answers are relatively easy to spot:
(A) is reversed - the argument is opposed to the principle!
(B) incorrectly states that the the principle "has been adopted." And, the consequences that are discussed are actually hypothetical ("would mean"), not, as (B) suggests, actual consequences that have happened.
(C) mistakenly suggests that the argument concludes that the consequences it notes are not necessarily going to happen. The argument states that "those with the least skill...would be the ones..." - there's no may or may not occur happening there!
(D) nails it! If you reward people in proportion to their effort, undesirable consequences - people with the least skill are the most incentivized - would follow. Notice that this answer correctly states "would follow," not "have followed" as (B) suggests.
(E) introduces the idea of how uniformly the principle could be applied - this is not discussed!
Does that clear it up?
