The correct example about the relationship between the insect hormones ecdysteroid and PTTH is interaction of the endocrine and nervous system. Hence, Option A is correct.
ENDOCRINE SYSTEM:
It is a complex system which is under hormonal control. Hormones are released by the glands and it cordinates body functions from metabolism to growth and development.
NERVOUS SYSTEM:
It is a complex system consisting of organised group of cells called neurons that carry messages from brain and spinal cord to other various body parts.
As PTTH (prothoracicotropic hormone) stimulates prothoracic gland of an insect that triggers the release of ecdysone hormone for the stimulation there should be an neuroendocrine mechanism. Thus, Option A is correct.
