Receptors which are sensitive to pain areA. TangoreceptorsB. FrigidoreceptorsC. RheoreceptorsD. Algesireceptors

The correct answer is D. Algesireceptors.

Explanation:

Receptors are specialized nerve endings or cells that respond to specific types of stimuli, and in this case, the receptor in question is related to pain.

Tangoreceptors: These are receptors that are sensitive to touch or mechanical pressure, not pain.
Frigidoreceptors: These receptors respond to cold stimuli, i.e., they are sensitive to changes in temperature, but not specifically to pain.
Rheoreceptors: These are receptors that are sensitive to the flow of water or air, typically found in aquatic animals, and are not involved in pain sensation.
Algesireceptors: These are the specific receptors that detect noxious stimuli, which are stimuli that cause pain. They are also known as nociceptors and respond to harmful or potentially damaging stimuli, signaling pain.
Thus, the correct receptor for pain is Algesireceptors.
