D. Darleen chose Tara, Holly, and, Marlene as her lab partners.

Respuesta :

Your answer is B I found a large, smooth ,rock at the beach yesterday because it is not D because theirs a punctuated after and its not A because it slows the sentence down when it came down to B,or C I choose B because the puntions seem in the right place.

Years your answer is B.

P.S if not B choose C but I'm with C.
