The shrinking of the pupil in bright light is what type of response?

Answer and explanation

Correct answer: Reflex response

Bright light is a stimulus detected by the eye. The pupil then constricts automatically, reducing the amount of light entering the eye and helping protect the retina. Because this response is rapid, automatic, and not dependent on conscious decision, option A is correct. Digestion, growth, and excretion are different physiological processes and do not describe the pupil's immediate response to light.
