Answer: C) To join two independent clauses without a coordinating conjunction.
Explanation: A comma splice is when a comma is used in between two independent clauses without a coordinating conjunction (ie and, but, or, etc). It is considered a sentence fragment and can be corrected in several ways; one of which is to replace the comma with a semicolon. This joins the two independent clauses without needing to insert a coordinating conjunction or break the sentence down into two separate sentences.
