Advertisers are often criticized for their unscrupulous manipulation of people's tastes and wants. There is evidence, however, that some advertisers are motivated by moral as well as financial considerations. A particular publication decided to change its image from being a family newspaper to concentrating on sex and violence, thus appealing to a different readership. Some advertisers withdrew their advertisements from the publication, and this must have been because they morally disapproved of publishing salacious material.
Which one of the following, if true, would most strengthen the argument?
(A) The advertisers switched their advertisements to other family newspapers.
(B) Some advertisers switched from family newspapers to advertise in the changed publication.
(C) The advertisers expected their product sales to increase if they stayed with the changed publication, but to decrease if they withdrew.
(D) People who generally read family newspapers are not likely to buy newspapers that concentrate on sex and violence.
(E) It was expected that the changed publication would appeal principally to those in a different income group.

"there is evidence ... some advertisers are motivated by moral as well as financial considerations." They're trying to be nice, and tip you off to the possible alternative explanation for why the advertisers would switch publications. Answer choice (C) suggests that the advertisers ignored their financial considerations, thus supporting the explanation that the advertisers switched for moral considerations.
Let's look at the incorrect answer choices:
(A) doesn't explain why! Maybe their financial considerations would prompt them to advertise in a family newspaper. We just don't know why they would want to stay with a family newspaper.
(B) fails to explain why just like answer choice (A).
(D) undermines the argument by providing a financial consideration to be aware of.
(E) undermines the argument by providing a financial consideration to be aware of.
