Which of the following combinations correctly matches the vitamin with its function and deficiency disorder?
Vitamin B12 - Aids nerve function and red blood cell formation - Deficiency causes Pernicious anaemia
Vitamin A helps form vision pigments and its deficiency causes night blindness – not calcium absorption or scurvy.
Vitamin D promotes calcium absorption and its deficiency causes rickets – pellagra is due to lack of niacin (B3).
Vitamin C is needed for collagen formation and its deficiency causes scurvy; blood clotting is the role of vitamin K.
Vitamin B12 (cobalamin) supports nerve function and red blood cell formation, and its deficiency causes pernicious anaemia – a fully correct match.
Hence, Vitamin B12 - Aids nerve function and red blood cell formation - Deficiency causes Pernicious anaemia.
