• A. Receptor, affectors, effectors
• B. Brain, spinal cord, effectors
• C. Receptors, integrators, effectors
• D. Receptors, integrator, effectors

Answer 1

The correct option is C Receptors, integrators, effectors

When the body system maintains constant internal environment by adjusting their physiological activities is called as homeostatic regulation. This process requires three components such as receptors that perceive the stimulus from the external environment, integrators that regulate the biological process with respect to the stimulus and effector are the organs or cells that give a response to the stimulus for homeostasis. Thus, the correct answer is option C.
