Question

La señora Vargas, por favor. a. ¿Está Manuel? c. Está sonando. b. ¿De parte de quién, por favor? d. Oye el tono.

Answer 1

Right answer:

b. ¿De parte de quién, por favor?

The context of this dialogue takes place when someone calls up to a place. Perhaps Mrs. Vargas lives or works here. In Spanish, when you call up to a place it is common to use the formula:

Name of the person you want to talk, + por favor

So if the person who picks up the receiver in the other side is not the person you need to talk, he would say the question:

¿De parte de quién, por favor? that translates into From who?, please?
