Too bad there's not the options, but the answer must be the hydroxyl and carbonyl group.
The solubility of sucrose in water as well as organic solvents is very high. In non-aqueous solvents is generally lower. On the other hand, sucrose is not soluble in nonpolar solvents. This solubility in the polar solvent as well as the water is due to the hydroxyl (-OH) and carbonyl (-C = O) functions creating hydrogen bonds with the solvent molecules making it easier to dissolve.
The correct answer is "<span>the blood vessels of the dermis have undergone vasodilation, bringing a greater volume of blood to the skin"
This is because heat signals the temperature regulating center of the hypothalamus then the hypothalamus will respond to that signal by activating the sympathetic nervous system causing the vasodilation of the cutaneous blood vessels leading to more blood flow essentially cooling the skin by letting more heat to the outside environment.</span>
