I gave my students this multiple choice question: What would best regulate the temperature of an overheated body?

Only one answer is correct among these 4 choices:
- a decrease in sweating
- a decrease in the breathing rate
- a dilation of blood vessels in the skin
- an increase in heart rate

Could you tell me which one is correct?

a dilation of blood vessels in the skin
