Which one of the following pairs is not correctly matched? Vitamin Role
A. Vitamin B12 anti anaemic factor
B. Vitamin C antiscorbutic factor
C. Vitamin D anti sterility factor
D. Vitamin K antihaemorrhagic factor

Correct answer: (c) C

Explanation

Vitamin D promotes intestinal absorption of calcium and phosphate; its deficiency causes rickets, not sterility.

The anti-sterility factor is actually Vitamin E, so the Vitamin D pairing is wrong.

B12 (anti-anaemic), C (antiscorbutic) and K (antihaemorrhagic) are all correctly matched.
