Answer:
fragment
Explanation:
Unlike sentences, "fragments" do not give a complete thought or idea. They are incomplete, and come as a part of a sentence. Besides this, they could also be lacking in a subject or a predicate.
"If you choose to be competitive" is particularly a "dependent clause" (subordinating clause), which used a subordinating conjunction, "if." As a subordinating clause, it should be attached to a main clause in order to become a complete sentence.
