If the winner of a promotional contest is selected by a lottery, the lottery must be fair, giving all entrants an equal chance of winning. Since 90 per cent of the winners selected by the lottery in a recent promotional contest submitted their entry forms within the first 2 days of the 30-day registration period, it is clear that this lottery did not meet the fairness requirement.
Which one of the following, if true, most strengthens the argument?
A. The family members of the organizer of the contest were not permitted to participate in the contest.
B. The manner in which the contest winner would be selected was publicized prior to the selection of the winner.
C. The contest entry forms were submitted at a consistent rate throughout the registration period.
D. The rules of the contest were posted conspicuously by those who organized the contest.
E. The number of people entering the contest far exceeded the expectations of the contest organizers

Decoding the passage:
The author concludes that because 90% of the winners were people who submitted their entry forms within the first 2 days of the 30-day registration period, the lottery did not meet fairness requirements.
The question stem asks us to strengthen the argument, i.e., we need to select the answer choice that further proves or confirms the validity of the author's conclusion.
(A) This answer choice weakens the argument, if anything. Because if the family members were to partcipate the organizer might want to tip the scale in their favour to win the lottery and this could possibly indicate rigging the lottery, but since they are NOT permitted to participate this weakens our conclusion that the lottery isn't fair.
(B) This answer choice does not affect the argument. It means that the organizers annouced publically how they would select the contest winners.
(C) Correct answer: If the entry forms were submitted consistently over the 30 days, but 90% of the winners came from those who submitted within the first two days, this strongly suggests that the lottery was biased toward early submissions. This strengthens the argument that the lottery was unfair.
You could also consider a scenario where all the entry forms were received during the first two days. In this case, there would be no question of the lottery being unfair, which would weaken our conclusion. By ruling out this possible weakener, our answer choice strengthens the argument further.
(D) This answer choice does not affect the argument. All it means is that that the rules of the contest were clearly visible to all the participants
(E) This answer choice does not affect the argument. The number of participants and the organizers' expectations have nothing to do with the fairness of the lottery.

Got it. I don't know how difficult this question was, but even after attempting it and going through your solution a couple of times, it took me a while to wrap my head around how C complements the fact that 90% of winners came from early submitters. How the absence of C would weaken the conclusion is what did the job for me. Thanks!
