Answer: A: Comma splice
Explanation:
When we put together two independent clauses, certain connectors or specific punctuation are necessary for them to sound as if they belong together. A comma splice happens when we use a comma where there should be a colon or a semicolon, or even a conjunction. That's what happens in the structure we are analyzing here. The proper punctuation would be: "The 1959 convertible Cadillac is one of a kind; a famous actor drove it."
Additional information:
A fused sentence happens when we put together two independent clauses with no punctuation or conjunction to connect them. Example: The kitchen was small it smelled of onions.
A fragment is a group of words that looks like a sentence but lacks something essential to make sense. Example: Sees her mother (there is no subject).
A dangling modifier happens when a word, phrase, or clause describes something or someone, but it is not clear to what or whom they refer. Example: Crying, she gave the baby back to his mother (we don't know for sure who was crying: the baby, the person holding it, or the mother).
