The correct option is C Workers
Worker bees, which live only around 35 days in summer, make wax from about the 10th day of their lives to the 16th. When workers are roughly 10 days old, they develop special wax-producing glands in their abdomens. The glands convert the sugar in the honey into wax, which seeps through small pores in the bee’s body leaving tiny white flakes on its abdomen. These bits of wax are then chewed by the bees. The chewed wax is added to the construction of the honeycomb. Hence, option C is correct.
