A) Chemoreceptors
B) Photoreceptors
C) Proprioceptors
D) Mechanoreceptors
Photoreceptors
Specialized cells located in the retina of the eye that convert light into electrical signals, enabling vision.
Penlight
A small, lightweight flashlight used in medical examinations to check patients' pupil response or throat.
Mechanoreceptors

Final Answer :
B
Explanation :
Photoreceptors located in the retina of the eyes detect visible light.Proprioceptors in the skin,muscles,tendons,ligaments,and joint capsules coordinate input to enable an individual to sense the position of the body in space.Chemoreceptors are located in the taste buds and epithelium of the nasal cavity.They play a role in taste and smell.Thermoreceptors in the skin detect variations in temperature.Mechanoreceptors in the skin and hair follicles detect touch,pressure,and vibration.
