Correct option is D
Explanation-
Eusocial societies (like those in bees, ants, and termites) are defined by the highest level of social organization in animals. Their key characteristics include:
1. Reproductive division of labor: Only a few individuals (e.g., queen) reproduce. Most others (workers) are sterile or non-reproductive.
2. Overlapping generations: Multiple generations live together and cooperate.
3. Cooperative care of young: Offspring are cared for by individuals other than their parents.
These societies do NOT have equal reproductive opportunities — in fact, inequality in reproduction is a hallmark feature.
Other options -
Option a - Altruism – Common in eusocial systems (workers sacrifice reproduction to help the queen).
Option b - Kin selection – Explains why non-reproductive individuals help close relatives.
Option c - Guarding against intruders – Protection of the colony is crucial and commonly observed.
Correct Option: d - Equal reproductive opportunities
