Receptors that respond to cold are called
Caloreceptors
Frigido Receptors
Baroreceptors
Tangoreceptors
As we have learnt:
Thermoreceptors:
Caloreceptors: respond to heat, for example, Ruffini’s corpuscles
Frigido Receptors: respond to cold, for example, Krause’s corpuscles
Hence, the correct answer is option b.
