Your answer should be lemon juice, but If I am wrong it could be sodium hydroxide, but I'm pretty sure its lemon juice. I hope this helps!

Cutaneous receptors are:

• Pacinian corpuscles-These are types of mechanoreceptor (response to mechanical  stimuli such as pressure or vibration). They are nerve endings in the skin that are sensitive to vibration and pressure

• Merkel's disc-These are types of mechanoreceptors, nerve endings that are sensitive to mechanical pressure, position, and sustained touch (shapes and edges of objects).

•Ruffini's end organ- These are types of mechanoreceptors slowly adapted that detects skin stretch.

•Meissner's corpuscles- These are types of mechanoreceptors, nerve endings responsible for sensitivity to light touch (changes in texture).
