Hoy vamos a ver un espectáculo de ballet en el a. actor b. director c. camerino d. teatro

Answer : D.) teatro

Explanation: The preposition "en" tells us that it refers to a place, but "A. actor" and "B. director" are people, so they do not fit with this preposition, "C. camerino" is a place inside a theater where artists prepare themselves before going on stage, dress and make up There it is not possible to see a ballet show, so the only logical option is D. teatro, which is a place where ballet shows are performed.

Hope this helps!
