In English this means: what do you ask for in the movies? I ask for candy.
The correct option is number 1 because the question is being made to "me" and the verb "pedir" is conjugated in the firs person of the singular. All the other options have the verb conjugated differently. "Piden los dulces" means "they ask for candy". "Pide los dulces" means "he or she asks for candy". "Pides los dulces" means "you ask for candy".
