Choose the best response to the question below.¿Cuántos días hay en una semana?

The question asks how many days there are in a week. In Spanish, “hay” is used to say that something exists or is present, so “Hay siete días en una semana” means “There are seven days in a week.” “Están” and “son” do not fit this phrasing, and “hayan” is not the correct verb form here.
