Vitamin B is described as containing biotin, which forms the basis of which cells?

• A. Provides antioxidant protection
• B. Contain biotin, which forms the basis of skin hair and nail cells
• C. Heals wounds rapidly
• D. Inhibits sebum production

Answer: (B)

Biotin, a B vitamin (B7), serves as a coenzyme in key metabolic processes and is closely linked to the health of keratin-containing structures. Because biotin supports the growth and maintenance of skin, hair, and nails, the statement that it forms the basis of skin, hair, and nail cells is the best description. The other options describe roles not specifically tied to biotin—antioxidant protection is typically linked to vitamins like C and E, wound healing is strongly associated with vitamin C and minerals like zinc, and sebum production isn’t directly controlled by biotin.
