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.
