Which vitamin can be synthesized in the body from beta-carotene?

The correct choice is Vitamin A, which can be synthesized in the body from beta-carotene. Beta-carotene is a type of carotenoid, a pigment found in many fruits and vegetables that gives them their orange and yellow colors. When consumed, beta-carotene is converted by the body into retinol, which is a form of Vitamin A. This process is essential since Vitamin A plays a crucial role in several bodily functions, including vision, immune function, and skin health.

Vitamins B12, C, and D cannot be synthesized from beta-carotene. Vitamin B12 is primarily obtained from animal sources and is vital for nerve function and the production of DNA and red blood cells. Vitamin C is found in various fruits and vegetables and is important for the growth and repair of tissues, as well as the functioning of immune health. Vitamin D is synthesized in the skin through exposure to sunlight and can also be obtained from certain foods; it plays a key role in calcium absorption and bone health. Therefore, the ability of the body to convert beta-carotene into Vitamin A distinguishes it from these other vitamins.
