Solution
The correct option is C Production of lac
Apiculture or bee-keeping is the rearing and management of honeybees for obtaining honey and beeswax. The place where the honeybees are reared is known as an apiary. Honey bees are of great economic importance because they yield valuable products like honey and beeswax.
• Honey is made from the nectar that the honeybees collect from the flowers.
• Beeswax is secreted by the wax glands located in the abdominal segments of worker bees (sterile females).
• Honey bees collect pollen and nectar as food from different flowers. In doing so, they also pollinate the flowers. Hence, they act as agents of pollination and help in the transfer of pollen grains from the anther of one flower to the stigma of another flower on the same plant or another plant.
Lac is not produced by honeybees. It is a scarlet coloured resinous secretion of a small insect known as Laccifer lacca. It is used as a sealing wax and stiffening agent.
So, the correct answer is 'production of lac'.
