Respuesta :

The answer is C. It's C because D means a group of people going and B means your asking a question.
Yo (voy) a comer en la concina. Yo means I and it is first person so it cannot be (A) because it is for El/Ella, and it is not (B) either because it is also for El/Ella but in past tense or (D) because it is They/Them. Therefore, the answer is (C).
