A
Meissner’s corpuscle
B
Pacinian corpuscle
C
Thermoreceptors
D
Nociceptors
Explanation: 

Detailed explanation-1: -Meissner corpuscles consist of a cutaneous nerve ending responsible for transmitting the sensations of fine, discriminative touch and vibration.

Detailed explanation-2: -Merkel discs and Meissner corpuscles are located near the surface of the skin at the dermal–epidermal junction, are highly sensitive to localized vertical pressure, and contribute to the sense of light touch.

Detailed explanation-3: -Tactile (Merkel) discs are in the deepest epidermis, acting as light touch receptors. Hair follicle receptors wrap around hair follicles, and are light touch receptors detecting hair bending. All encapsulated nerve endings have one or more fiber terminals of sensory neurons in a connective tissue capsule.
