Answer:
Option a. effector
Explanation:
Effectors acts in response to the commands of the control center in negative feedback.
Negative feedback is when the system responds to the stimulus in such that it reverses the direction in which change occurs thus maintaining homeostatis (stability).
An example of negative feedback is thermoregulation in which body temperature is regulated with skin acting as receptor to communicate information to control center (brain); sweat glands and blood vessels acting as effector which results in regulation of body temperature.
The Effectors either supports or opposes the stimulus.
