A. Insert a semicolon after the word paintings
The answer to your question would be that the version of the sentence that has correctly placed commas is the following one: Noah, who draws comic books in his free time, wants to write a graphic novel. That is, your answer would be option A.
The clause set off with the commas is a non-restrictive relative clause. This means that it provides information which is considered non-essential to the meaning of the sentence and therefore can be dropped without altering its meaning. That is why they are set off with commas, parentheses or dashes.
