i\(\to\)c, ii\(\to\)d, iii\(\to\)a, iv\(\to\)b
i\(\to\)c, ii\(\to\)d, iii\(\to\)b, iv\(\to\)a
i\(\to\)d, ii\(\to\)c, iii\(\to\)b, iv\(\to\)a
i\(\to\)c, ii\(\to\)b, iii\(\)d, iv\(\to\)a
i → c, ii → d, iii → b, iv → a
The correct matching of vitamins with their deficiency/condition is: i → c, ii → d, iii → b, iv → a.

Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
