摘自beat the gmat：

(C)The advertisers, when questioned, admitted that their clients would lose significant revenue as a result of the advertisements being withdrawn.

This answer choice is the only one that in any way supports the argument. If the advertisers would lose revenue as a result of withdrawing the advertisements there must be some non financial reason for their having withdrawn the advertisements. While this answer choice does not clearly point to one reason, it does eliminate a reason. So in a sense it supports the conclusion, at least more than any of the other answer choices do.

(D)The advertisers all placed new advertisements in other mobile apps that had no such concerns regarding user privacy.

If anything this weakens the conclusion in that it conflicts with the idea that advertisers are concerned with user privacy.
