Answer: (C)

Verified step by step guidance

1. Begin by understanding the function of each type of receptor mentioned in the problem. Receptors are specialized cells or nerve endings that respond to specific stimuli and send signals to the brain, which interprets these signals as sensations.
2. Nociceptors are responsible for detecting pain. They are activated by potentially harmful stimuli, such as extreme temperatures or mechanical damage, and trigger the sensation of pain.
3. Thermoreceptors detect changes in temperature. They are sensitive to heat and cold, allowing the body to perceive temperature changes as sensations.
4. Photoreceptors are found in the retina of the eye and are responsible for detecting light. They enable the sensation of vision by converting light into neural signals that are interpreted by the brain.
5. Proprioceptors, unlike the other receptors, do not trigger a conscious sensation. They are involved in sensing the position and movement of the body, providing information about muscle tension and joint position to help maintain balance and posture without triggering a direct sensation.
