From the following selections, choose the correctly punctuated sentence. a. Can you please send me the confidential folder? b. Can you please send me the confidential folder— c. Can you please send me the confidential folder.

The correct answer is:

Can you please send me the confidential folder? (a.)

Explanation:

The statement is a question, which needs to be answered, and in order to write a question, the writer add the punctuation mark "?", at the end of the sentence to denote that what is being said is a question, and if it is wrtten exactly in the speaker's words (verbatim), not in reported speech.

The sentence started with "Can you", and that automatically changes the whole sentence into a question, no matter the arrangement of words that follow. If the speaker had said, " Please send me the confidential folder", there would be no need for a question mark (?), because it is not a question, also if the statement was written in reported speech like " He asked if I could send him the confidential folder", then there would be no need for a question mark

other words used to start a question are, why, how, who, when, where, etc. and when used to start a sentence in the the speakers words verbatim, it is accompanied by a question mark.
