Answer:
A. The mandate that high school seniors at Central High volunteer for a public service project is a welcome change to the high school graduation requirement.
Explanation:
Option A is the best choice for the conclusion paragraph. It restates the claim, but doesn't summarize the entire essay. The conclusion paragraph should summarize the entire essay, but not in the first sentence. Options B and C add in extra information. Conclusions should not add new facts or details, but rather remind the reader of those most important to proving the claim correct.
