Right.

i disagree (tell me if im wrong tho) but shuldnt the t in the YMCa be capitalized?

The correct answer is C. "Mr. Jones visited the YMCA before becoming a member." This sentence is correctly punctuated. Let's go through the options and analyze how to identify the correct answer:

A. "Mary remembered to buy milk didn't she?" - This sentence is incorrectly punctuated. It should be "Mary remembered to buy milk, didn't she?" The comma is necessary to separate the independent clause "Mary remembered to buy milk" from the tag question "didn't she?"

B. "The company held it's annual party at the convention center." - This sentence is incorrectly punctuated. "It's" is the contraction of "it is," but in this context, it should be possessive. The correct form would be "its" without an apostrophe. So, the correct sentence would be "The company held its annual party at the convention center."

[C. "Mr. Jones visited the YMCA before becoming a member."] - This sentence is correctly punctuated. There is no error in the punctuation. The period at the end of the sentence is used to indicate the end of a complete thought.

D. "The local police asked the F.B.I. to assist with the case." - This sentence is correctly punctuated. The abbreviation "F.B.I." is punctuated with periods because it stands for "Federal Bureau of Investigation."

Therefore, the only sentence correctly punctuated is option C: "Mr. Jones visited the YMCA before becoming a member."
