Which of the following vitamins is mismatched with its function?

A) Vitamin D - bone growth
B) Vitamin A - rhodopsin synthesis
C) Folate - synthesis of clotting factors
D) Vitamin C - collagen synthesis
E) Vitamin B₁₂ - red blood cell production

EVitamin C is correctly matched with collagen synthesis, and Vitamin D with bone growth. Vitamin A is indeed involved in rhodopsin synthesis, which is crucial for vision. Vitamin B12 (which seems to be what "Vitamin B₁₂" is attempting to represent) is essential for red blood cell production. However, Folate (Vitamin B9) is not involved in the synthesis of clotting factors; instead, it is crucial for DNA synthesis and repair, and red and white blood cell production in the bone marrow. Vitamin K is the vitamin associated with the synthesis of clotting factors.
