Used to define/describe a group of objects. Example: a flock of seagulls.

• A. Collective noun
• B. Proper noun
• C. Count noun
• D. Noun

Answer: (A)

A collective noun is used to name a group of individuals as a single unit. In your example, the word that defines the group is flock, so the phrase describes a group of seagulls as one entity. That’s why it’s the best fit here—it specifically names the group, not just any noun or a single name.

This differs from a proper noun, which is a specific name like a person or place (George, Atlantic Ocean). It also isn’t a generic noun category like a count noun, which describes nouns that can be counted individually (seagull, not the group as a unit). And it isn’t just any noun; it’s a noun that denotes a collection of individuals acting as a single unit.
