Explanation:
Hypothalamus is the thermostat of the body as it regulates and maintains body temperature by responding to external signals or stimuli and adjusts the body temperature in a close one to two degree of 98.6 degree.
The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.
Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.
Thus, the correct answer is a Complex neuroendocrine response.
The experimental protocol describes and determines materials, equipment, and procedures.
