#1) Select the appropriate response to the following question:
¿Qué programa prefieres ver en la televisión?
Answer: Out of all the options that are presented above the one that is the appropriate response to the question is Prefiero ver un drama. The reason being that the questions is directed to you (singular person). Prefiere is used to state that someone else prefers. Prefieren is used for more than one person. Prefieres would be appropriate in a question not an answer.
I hope it helps, Regards.
