Answer:
The correct one should be I'm pretty sure it's her's.
Explanation:
The correct answer to this question would be is a compound sentence. A compound sentence is when there are two parts of a sentence that can work alone as complete sentences, but which are combined into one sentence with the use of a conjunction (and, but, etc.). In this case, "I watched the movie" and "I didn't like it" can stand on their own as separate sentences. However, they are put together into one sentence by the word "but," a conjunction, which classifies this sentence as compound. I hope this helps you!
the answer is B the comma in between open {and} and makes it feel more natural
