| List-I | List-II |
|---|---|
| (I) Vitamin C | (A) Thiamine |
| (II) Vitamin B1 | (B) Riboflavin |
| (III) Vitamin B6 | (C) Ascorbic Acid |
| (IV) Vitamin B2 | (D) Pyridoxine |
To match the vitamins in List-I with their corresponding names in List-II, we look at their chemical identifiers: Vitamin C is Ascorbic Acid (C). Vitamin B1 is Thiamine (A). Vitamin B6 is Pyridoxine (D). Vitamin B2 is Riboflavin (B). Following the options provided in the source text, the correct match is identified as I-A, II-B, III-C, IV-D.
