What is the basic social structure of an ant colony?

• A. A queen, workers, and soldiers.
• B. A queen and drones only.
• C. Foragers and nest absent of queen.
• D. A solitary ant with no social structure.

Answer: (A)

Ants organize their colonies through division of labor and cooperative care—the queen lays eggs, workers care for the young and maintain the nest, and in many species soldiers stand ready to defend the colony. This combination of reproductive individuals (the queen), everyday laborers (the workers), and a defense-focused group (the soldiers) represents the basic social structure of an ant colony. Other options misrepresent how colonies sustain themselves: a setup with only a queen and drones excludes the crucial worker castes that perform daily tasks; a system with foragers and no queen can't reproduce and would not persist; and a solitary ant with no social structure contradicts the very nature of ants as eusocial insects.
