Answer: (A)

Verified step by step guidance

1. Begin by understanding the function of each type of receptor listed in the options.
2. Photoreceptors are specialized cells found in the retina of the eye that detect changes in light intensity and wavelength, allowing for vision.
3. Thermoreceptors are sensory receptors that respond to changes in temperature, helping the body perceive heat and cold.
4. Mechanoreceptors are responsible for detecting mechanical changes such as pressure, vibration, and touch.
5. Chemoreceptors detect chemical stimuli, such as changes in the concentration of substances in the blood or external environment.
