'C' is the best answer, not completely convincing though

A. Capeville, a neighboring city, has only one parking garage, though it was not filled every day of the month. Irrelevant.

B. In July, the Williamstown parking garage was full every day of the month. This Presents the same idea as in the prompt. If it was full in July/ August, it will be full in September as well. - Incorrect assumption

C. Williamstown is popular beach town and tourists across the nation flock to its beaches from June to August, but the city becomes virtually empty come September. This statement explains why the main city parking garage was full in August; It also explains why the garage will not be full in September.

D. This coming September, the Williamstown City Council is inaugurating the first annual September rock festival, which will feature performances throughout the month by popular musicians. Supports the conclusion.

E. The Grand Hotel, a popular hotel in Williamstown, expects to have a full garage the entire month of September. Irrelevant. We are only concerned with the main city parking garage.

My answer is C, which undermines the conclusion that the parking garage is full in Sept.

Official Explanation
The credited answer is (C).

If there is something external, the beach season, which would cause the garage to be full in August, but which will end at the end of August, then one of the principal factors filling the garage will itself come to an end, and there's no reason to expect the parking pattern to continue into September. Choice (C) is a very effective weakener.

Choice (A) is about a different town with a different situation. We know nothing about similarities or differences between the two towns. We can draw no conclusion about what this might imply about parking in September in Williamstown. Choice (A) is incorrect.

Choice (B) extends the pattern backward in time, but it leave mysterious any cause and whether that cause will continue or end. Choice (B) is incorrect.

Choice (D), by suggesting an event that could fill the parking in September, is a strengthener, and we need a weakener. Choice (D) is incorrect.

We don't know how big the Grand Hotel and its parking garage are, nor do we know how that parking garage compares in size to the main city parking garage. If the Grand Hotel parking garage were full, would be a sizeable number of cars that would not be parking in the main city parking garage? Who parks in either place, and what, if anything, is the relationship of these two groups? Choice (E) opens several questions, leaving them unanswered. It is not unambiguously either a strengthener or a weakener, so it is incorrect
