which error does the sentence make?
fused sentence
sentence fragment
comma splice
independent clause

The correct answer is sentence fragment.

You cannot call it a sentence because it is incomplete - it is rather a dependent, aka, subordinate clause. This means that it is not complete and that it cannot stand on its own. It needs to be a part of a larger, independent sentence, in order to make some sense and in order to be complete and called 'sentence.' This way, it is lacking a subject.
