The sentence that is punctuated correctly and has correct capitalization is: "Have you ever seen a shooting star?" asked Terry. This is the sentence that is correctly punctuated because the rule in quoting a question sentence is applied correctly. A question mark should be put inside the quotation marks. If a question mark is used, it is no longer necessary to put a comma.
