Solution
The correct option is C Juvenile hormone
Juvenile hormone (JH), produced by the corpora allata, regulates two important processes in insects. The first is development; as an insect develops, the degree juvenility of the next stage is determined by the amount of JH in the blood; the lower the JH, the more adult the next stage. The other function of JH is, in many insects, to regulate the production of eggs in the female's ovaries. Because mating behavior is often synchronized with the ovarian cycle, the mating behaviour and pheromone production to be linked with JH.
