Two independent clauses incorrectly joined are referred to as a fused sentence

The correct answer is option C (fused sentence).

Fused sentences are two independent clauses that run together as if they were only one. This is because they lack an appropriate punctuation mark such as a period or a semicolon. From the grammatical point of view, fused sentences are regarded as incorrect.
