I think you lack some information about this exercise. All of the following are grammatically correct. One of them implies Andrés suffers from Alzheimer´s:
Andrés: David, ¿quién le dio el menú?
David: El mesero se lo dio.
Andrés: David, ¿quién nos dio el menú?
David: El mesero nos lo dio.
Andrés: David, ¿quién me dio el menú?
David: El mesero te lo dio.
Andrés: David, ¿quién te dio el menú?
David: El mesero me lo dio.
If this is simply an artificially constructed "conversation" to illustrate the use of pronouns, then "nos" is, certainly one solution (the other being "te" for the first sentence and "me" for the second). Grammatically, the first could be "me" and the second "te" but this would imply that the Andres was exceptionally unobservant (or had sever short-term memory problems).
In practical terms, the conversation is silly. The person that received the menu would, surely, know who gave it to him and his companion (by virtue of being at the same table) would also know.
Nos fits both sentences.
