The correct answer is A. The sensation function of the skin involves responding to touch, pain, cold, heat, and pressure.

This function helps us navigate our environment and protect ourselves from potential harm.

Choices B, C, and D are incorrect:

B. Regulating internal body temperature is related to the thermoregulation function of the skin, not the sensation function.

C. Detoxifying the body by excreting excess water is not a primary function of the skin.

D. Absorbing water and essential nutrients is part of the absorption function of the skin, not the sensation function.
