Quizplus · Accepted Answer

Vitamin D is synthesized in the skin when it is exposed to sunlight. Therefore, someone who walks outdoors daily with light-weight clothing would be able to make sufficient amounts of vitamin D without having to eat foods containing the vitamin. Someone who always wears sunscreen when outdoors in the daytime (A) would not be able to synthesize enough vitamin D because sunscreen blocks UV light, which is necessary for vitamin D synthesis. Someone who works in an office in a northern urban area (B) would not receive enough sunlight exposure to synthesize vitamin D. Finally, someone with dark skin (D) requires more sunlight exposure than someone with light skin to synthesize the same amount of vitamin D because melanin impedes vitamin D synthesis.
