The correct option is A 1 and 3
The place where the honey bees are kept and reared for obtaining honey and beeswax is known as an apiary. This practice of rearing, caring and management of honeybees is known as apiculture.
Choosing an ideal location for the apiary is essential as it affects the survival of the honeybees, hence influences the yield of the honey.
Most apiaries are located near fruit orchards, public gardens or crop fields to ensure that the bees have sufficient supply of pollen and nectar. The nectar is a sugary liquid which serves as a source of energy. The pollens act as sources of proteins and other nutrients. The worker (sterile female) bees in a colony collect the pollen and nectar from flowers to feed the brood (eggs, larvae and pupae).
Hence statement 1 is correct.
As honey is produced from nectar, a larger amount of nectar collection helps to increase the production of honey. While collecting the pollen and nectar from different flowers, honeybees transfer pollen grains from the anther of one flower to the stigma of another flower. Hence, they facilitate cross-pollination and play a major role in the sexual reproduction of flowering plants (angiosperms). Keeping beehives in or near fields during the flowering season of crop plants increases cross-pollination efficiency and crop yield. It also helps in generating higher yield of honey.
So, statement 3 is correct.
Although the presence of trees and flowers does enhance the beauty of apiaries, this is not a reason for the apiaries being located near orchards, gardens or crop fields.
Hence statement 2 is incorrect.
The scent of the flowers does not help in the mating process between the queen (the only fertile female of the colony) and the drone (fertile male). The queen uses special chemicals known as pheromones to signal and communicate with the drones.
Hence statement 4 is incorrect.
