SCURVY is caused by deficiency of which vitamin?

SCURVY is caused by deficiency of which vitamin?

• A. Vitamin B12
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Answer: (B)

Scurvy comes from not having enough vitamin C, which is essential for making collagen, the main protein that holds our tissues together. Vitamin C acts as a cofactor for enzymes that hydroxylate the amino acids proline and lysine in collagen; without enough of it, collagen fibers are weak, leading to fragile blood vessels, gum disease, easy bruising, and poor wound healing. Humans can’t synthesize vitamin C, so it must be obtained from the diet (citrus fruits, berries, vegetables). Among the options, only vitamin C deficiency causes scurvy; deficiencies of B12, D, or K lead to different problems—B12 affects blood and nerves, D affects bone health, and K affects blood clotting.
