Match the nutrient with the disease caused by its deficiency.

Choose the most appropriate option from below :

Answer: C

The correct matching is i-c, ii-d, iii-b, iv-a.

Vitamin A deficiency causes night blindness (c).
Riboflavin (vitamin B2) deficiency causes glossitis, angular stomatitis and cheilosis (d).
Cyanocobalamin (vitamin B12) deficiency causes pernicious anaemia (b).
Niacin deficiency causes pellagra (a).

The last option has the first two pairs right but swaps B12 and niacin, giving pellagra to B12, which is the trap.
