Correct answer

D. The males do not have fathers and thus cannot have sons, but have a grandfather and can have grandsons.

Step-by-step solution

The sex determination in honey bees is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilised egg develops as a male (drone) by means of parthenogenesis. This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called a haplodiploid sex-determination system
