<span>Él es un compañero de clase is the right answer. The 1st sentence is ella but </span>compañero should be compañera. In the second one ella should not have an accent mark and in the last one el doesn't match with una.
Answer: Hablan
Explanation: B is hablamos, which will be used if it says we. C is habla, which is describing another person (singular). D is hablas, which is talking about you (tu). So the answer will be a, hablan, because it is talking about they, and in plural version. If its singular, it will be habla. Family consists of multiple members, so it wouldn’t be singular.
