Answer:
d. The person's blood vessels in the dermis have undergone
Explanation:
Humans are warm-blooded animals and maintain constant body temperature by using the energy produced during metabolism. To maintain constant body temperature, several thermoregulatory mechanisms operate. Skin is also involved in thermoregulation.
The thermoreceptors present in the skin layers sense the drop in the temperature of surroundings and the blood capillaries present in the dermis are narrowed. Constriction of blood vessels of the dermis occurs to reduce the blood supply to the skin and thereby prevent the heat loss from the body. Vasoconstriction of blood capillaries of the dermis and the resultant reduced blood flow impart pale appearance to the light-skinned person in winters.
