Which vitamin is provided by sunlight to the human body?
(A) Vitamin A

SUNLIGHT supplies vitamin D to the human body, or rather vitamin D3, the "sunshine vitamin." When skin is exposed to UVB rays of the sun, they transform 7-dehydrocholesterol into previtamin D3, and the heat of the body transforms the previtamin D3 into the actual vitamin D.
