I believe the correct answer from the choices listed above is the first option. A collective subject is a noun (functioning as the subject) that describes a group made of many parts. Examples are brood of chickens, drove of cattle, gaggle of geese, nest of bees, swarm of hornets and herd of buffalo.
Im pretty sure it would be c
D. to relate a noun or pronoun to another part of the sentence. Example: A girl from home. The preposition 'from' shows the relationship between the girl and home.
The answer is B. Hopes this helps.
