Cholesterol's involvement in vitamin synthesis is described as being a precursor for which vitamin?

Explanation:
Cholesterol acts as a starting material for making vitamin D in the skin. When skin is exposed to UV light, a cholesterol derivative called 7-dehydrocholesterol is converted to previtamin D3, which then becomes vitamin D3. This connection to cholesterol is unique to vitamin D among the listed vitamins, since vitamins A, E, and K are not produced from cholesterol in the body. So vitamin D is the vitamin linked to cholesterol as a precursor.
