The correct answer is A) I studied that when I was in sixth grade. In this independent sentence, the adverb clause is 'when I was in sixth grade'. An adverb clause is a subgroup of dependent clauses, meaning that it cannot exist on its own, outside of the main, independent clause. Just saying 'when I was in sixth grade' means nothing, it is incomplete.
Hope this helps :)
