Explanation:

A collective noun is illustrated as the noun that represents a group or collection(plural nouns) of people or objects. Such a noun is employed to refer to a group of people together as a whole. It usually accompanies a singular verb form and a singular pronoun along with it as they denote a single unit or entity. For instance, the words family, jury, swarm, bunch, etc. carry a singular verb form and are represented by a singular pronoun. Let us look at the given examples including some of these words:

'His family is well-off'

'Rima had a bunch of keys in her hand'

'The jury was not there when he reached'

All of them employ a singular verb form and therefore, it would require a pronoun also singular. Thus, option A is the correct answer.
