Answer:
b. sympathetic
Step-by-step explanation:
The feet have a specific type of sweat gland called eccrine sweat glands. These type of glands are located in many diverse parts of the body. What they have in common is that all of them are innervated by the sympathetic nervous system. Therefore, if the sympathetic activity increases, the glands on the feet will increase its activity as well. As a result, you will have sweaty feet.
