Solution

The correct option is B 2n, n
The principle behind the genetics of honeybees is that the female queen honeybees are formed from the fertilized eggs, Thus, there will be diploid number (2n) chromosomes. But, in the case of male honeybees (drones), there are only haploid number (n) chromosomes as they are formed from the process of parthenogenesis means unfertilized eggs.
