Answer:
The right answer is; Piden
Explanation:
Because the narrator in the sentence is referring to several people and the verb used is to ask; therefore, we must identify the number, person, gender, context and time in order to logically conjugate the verb within the sentence and have agreement with what is being expressed.
The correct answer is “se les olvido”
1. D) es
2. A) están
3. C) está
4. B) son
True, conjugation is making the verb agree with the subject
