Choice-A

Choice A is incorrect. Ends with a period. Might look correct if focusing only on the clause, but check if the sentence is actually a question overall.

Wrong No change

Choice B is incorrect. Semicolon plus exclamation mark is incorrect punctuation. Only one end mark is needed, and semicolons aren’t used before exclamation marks.

Wrong Are believed to be over two thousand years old;!

Choice-C

Choice C is correct. Uses a question mark, which may seem odd since the clause sounds like a statement. But think — is the entire sentence a question?
