Choice A: This answer choice features a comma splice error, joining two independent clauses with a comma. Thus, this answer choice is incorrect.
Choice B: This answer choice utilizes a semicolon to join an independent clause and a dependent clause. Thus, this answer choice is incorrect.
Choice C: This answer choice efficiently combines two ideas by expressing each of them in a complete sentence and joining them through a semicolon. This answer choice also maintains proper pronoun use, throughout the sentence. Thus, this answer choice is correct.
Choice D: In this answer choice, the pronoun "they" has no clear antecedent. Moreover, the use of the word "where" is incorrect; "where" is always used to refer to a specific point in space. Thus, this answer choice is incorrect.
Choice E: This answer choice repeats the pronoun ambiguity error found in Option D.
