C. Complete Sentence
Explanation:
A sentence fragment is just another term for 'incomplete sentence.' As the name indicates, it's merely a piece of a sentence that can't stand on its own. All sentences need to have at least one independent clause - that's a clause with at least one subject and one verb that can stand on its own as a sentence.
A comma splice results when a comma is incorrectly used to join two complete thoughts (meaning each thought has a subject and verb, and the thoughts could stand all on their own—otherwise known as “independent clauses”)
A complete sentence always contains a verb, expresses a complete idea and makes sense standing alone.
