Quotation marks, if appropriate, must be used before and after the sentence. They should be used in pairs. They denote actual spoken or written words taken from a person or other source.

"What a crime."

This answer would be a correct answer. The other choices come from actual statements, questions, or exclamations.

A quotation within a quotation would look a little different.

"The newspaper headline, ' What a crime !' was over dramatic."

Notice, the same rule applies, as the quotation marks are used in pairs.
