The correct option is C drones
A drone is a male honey bee whose primary role is to mate with an unfertilized queen. They do not do any work in the hive.
Queen bee is the largest member of the bee colony and she lays the eggs.
Worker bees are female members that are very hardworking and they build beehives; collect nectar from flowers and make honey.
There's no such thing as 'king bee' in bees.
