Choice B is the best answer. Both clauses in this sentence could stand alone as complete sentences, which means they are
both independent clauses. This choice uses a comma plus a coordinating conjunction to link them together, which is one of

Choice A is incorrect. This choice results in a run-on sentence error. Both clauses in this sentence could stand alone as
complete sentences, which means they are both independent clauses. A comma by itself is not enough punctuation to link
two independent clauses. Choice C is incorrect. This choice results in a run-on sentence error. Both clauses in this sentence
could stand alone as complete sentences, which means they are both independent clauses. Independent clauses can only
be linked in a few ways, including with a comma plus a coordinating conjunction. This choice uses the coordinating
conjunction “and,” but it is missing the comma beforehand. Choice D is incorrect. This choice results in a run-on sentence
error. Both clauses in this sentence could stand alone as complete sentences, which means they are both independent
clauses. Independent clauses need to have certain kinds of punctuation marks between them. This choice doesn’t use any
punctuation between the two clauses.
