Verified step by step guidance

Understand the role of the skin in vitamin synthesis: The skin is involved in the synthesis of certain vitamins, particularly when exposed to sunlight.

Identify the vitamin synthesized by the skin: The skin synthesizes Vitamin D when it is exposed to ultraviolet (UV) rays from the sun.

Differentiate between the vitamins listed: Vitamin B12, Vitamin K, and Vitamin C are not synthesized by the skin. Vitamin B12 is obtained from dietary sources, Vitamin K is produced by gut bacteria, and Vitamin C is obtained from fruits and vegetables.

Recognize the process of Vitamin D synthesis: When UV rays hit the skin, they convert 7-dehydrocholesterol, a compound in the skin, into previtamin D3, which is then converted into Vitamin D3.

Conclude that the skin's role in vitamin synthesis is specific to Vitamin D, making it the correct answer in this context.
