Choice A: This answer choice connects two independent clauses with a comma, creating a run-on sentence. Thus, this answer choice is incorrect.
Choice B: This answer choice repeats the error found in Option A. Additionally, this answer choice changes the meaning of the sentence by introducing new information through the phrase "that wasn’t the best thing to do". Thus, this answer choice is incorrect.
Choice C: This answer choice correctly connects two independent clauses by using a comma followed by appropriate conjunction and preserves the intended meaning of the sentence. Thus, this answer choice is correct.
Choice D: This answer choice repeats the error seen in Options A and B. Thus, this answer choice is incorrect.
Choice E: This answer choice repeats the error seen in Options A, B, and C. This answer choice also changes the meaning of the sentence by using the word "decided", rather than one of the words "occurred", "realized", or "concluded"; the word "decided" carries a more active connotation that alters the intended meaning of the sentence, which is that the group came to understand that "Jane was more articulate and more diplomatic".
Hence, C is the best answer choice.To understand the concept of "Comma Splices and Run-ons on GMAT", you may want to watch the following video (~6 minutes):
