Collective nouns are nouns that refer to groups.

• A. Collective Nouns
• B. Proper Nouns
• C. Abstract Nouns
• D. Count Nouns

Answer: (A)

Nouns are categorized by what they name, and one category names a group of individuals or things. That category is the collective noun, which represents a group as a single unit (like team, committee, or flock). The statement describes collective nouns precisely as nouns that refer to groups, so this choice is the best fit. The other options point to different noun types: proper nouns name specific people, places, or organizations and are always capitalized; abstract nouns name ideas, qualities, or states; count nouns are about things that can be counted, not about naming a group.
