Explanation:

It is a sentence fragment. It does not show a complete action.

A sentence fragment is a group of words that looks like a sentence, but actually isn't a complete sentence. Sentence fragments are usually missing a subject or verb, or they do not express a complete thought. While it may be punctuated to look like a complete sentence, a fragment cannot stand on its own.
