c.The audience was ready for the game to begin.
Step-by-step explanation:
A collective noun is a name that refers to a set of objects or living beings of the same species grouped under the same spatial conditions. Words like team, audience and choir are considered collective nouns. These nouns are considered in the pulral, when group members are not focused on the same activity and can act independently. In this case, we can say that "choir" is the option that shows a collective noun in the plural, because choir members can sing the hymn independently, in their own way.
