The sentence that contains a comma splice is:
"I wish I had remembered my jacket, it's so cold outside!"
Explanation:
1. A comma splice occurs when two independent clauses are joined by a comma without a coordinating conjunction (e.g., and, but, or).
2. In this sentence, "I wish I had remembered my jacket" and "it's so cold outside!" are both independent clauses that can stand alone as separate sentences.
3. The comma between "jacket" and "it's" attempts to connect these two independent clauses, making it a comma splice.
4. To correct the comma splice, you could use a semicolon, period, or conjunction like "because" to join the clauses properly.
