Is Haplodiploidy a Necessary Condition for the Evolution of Eusociality

Multiple Choice

Is haplodiploidy a necessary condition for the evolution of eusociality?

A) Yes; true eusociality is found only in the hymenoptera, all of which are haplodiploid.
B) Yes; eusociality can only evolve when indirect fitness is as high as occurs between haplodiploid sisters.
C) No; eusociality is also found in organisms that do not have a haplodiploid genetic system, such as naked mole rats.
D) No; eusociality has evolved in every major animal lineage.
