Answer

Answer:

A. the name of the singer is unknown

Brief Explanations:

In passive voice, the focus shifts to the action and the object (here, "a solo" and the action "was sung"), which is useful when the doer (singer) is unknown. The other options relate to song type, concert length, or holiday type, which aren’t reasons for passive voice use here.
