Answer:
The correct answer will be option-B
Explanation:
Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.
The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.
The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.
Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.
Thus, Option-B is the correct answer.

Answer:
Positive and Negative feedback
Explanation:
In positive feedback, the released product in the process allows the increase in the product. For example- during the time of child birth, crevix due to more pressure allows contractions and release of oxytocin. The hormone oxytocin causes more contraction.
In negative feedback, the released product causes decline in the level. For example, the temperature regulation mechanism, high temperature cause start sweating when there is temperature drop then low temperatures causes vasoconstriction and temperature increased again.
