Cholesterol is needed for the synthesis of which vitamin?

Explanation:
Cholesterol provides the starting material for vitamin D synthesis in the skin. Specifically, the skin contains 7-dehydrocholesterol, a cholesterol-derived compound that, when exposed to UVB light, is converted into vitamin D3 (cholecalciferol). This makes vitamin D unique among these vitamins in its dependence on a cholesterol-derived precursor for its production. The other vitamins—A, E, and K—are obtained or synthesized through different pathways that do not rely on cholesterol as a precursor.
