The correct answer as to which component of thermoregulation allows the body to maintain homeostasis after jumping into a tub of hot water would be that the blood vessels in the skin (dermis) will dilate.
The temperature of the body would normally want to rise beyond the set point (normal body temperature) if a person jumps into a tub of hot water. When this happens, the body's homeostasis kicks in. The receptor (the skin) sends a message to the control center (the brain) and in turn, the control center sends message to effectors (the blood vessels).
The blood vessels that carry blood to the skin (the dermis) are told to dilate so that more blood gets to the skin. When this happens, more heat is lost to the surrounding from the blood leading to the temperature of the body getting back to the set point.
