"They get their name from the fact that they work together (co-) and relate one sentence element to another. Correlative conjunctions include pairs such as "both/and," "either/or," "neither/nor," "not/but" and "not only/but also."".
Since correlative conjunctions work to bring sentences together in <em>pairs, </em>not just one conjunction, the answer is D).Both the track team and the volleyball team enjoyed a winning season.
The reason why is because that's the only sentence with two conjunctions (Both the track team and the volleyball team enjoyed a winning season.)
