Correct Answer is: C
Choice C correctly uses a conjunction to combine the two independent clauses. A comma alone is not enough to combine two independent clauses. The semicolon in choice D is incorrect. A semicolon can be used to combine two independent clauses if they are closely related or if the second clause explains or clarifies the first clause. However, the two clauses in the given sentence are not closely related. Therefore, the most effective revision is choice C, which uses a conjunction to combine the two independent clauses.
