The ant caste system best described as consisting of which groups?

• A. Soldiers, drones, workers
• B. Queen, male reproductive, workers
• C. Queen and drones
• D. Workers only

Answer: (B)

Ant colonies organize individuals into castes based on their reproductive role and duties. The three core groups are the queen (the primary egg layer), the male reproductives (drones whose job is to mate with queens), and the workers (non-reproductive females that perform foraging, brood care, and nest maintenance). This combination captures the essential structure of most ant colonies: a reproductive couple (queen and males) plus a large non-reproductive workforce. Some species do have specialized soldiers, but that is not a universal, fundamental caste on par with the queen, drones, and workers. Choosing options that omit workers or reproductives or replace them with soldiers doesn’t reflect the typical, broad description of an ant caste system.
