Correct Answer: D
Solution : The correct option is D .
Exposure to sunlight helps the skin synthesize vitamin D. When ultraviolet B (UVB) rays from the sun interact with the skin, a compound in the skin is converted into vitamin D3, also known as cholecalciferol. This vitamin plays a crucial role in maintaining healthy bones and teeth, supporting the immune system and regulating calcium and phosphorus in the body.
