Match List - I with List - II. 

Choose the correct answer from the options given below :

Vitamins are often referred to by both a number (or letter) and a specific chemical name. To answer a matching question, first recall the standard correspondences:

• Vitamin B₁ is chemically known as $$\text{Thiamine}$$.
• Vitamin B₂ is chemically known as $$\text{Riboflavin}$$.
• Vitamin B₆ is chemically known as $$\text{Pyridoxine}$$.
• Vitamin C is chemically known as $$\text{Ascorbic acid}$$.

Now compare these facts with List - II:

Case A (Vitamin B₁): Thiamine is listed as III ⇒ A → III.

Case B (Vitamin B₂): Riboflavin is listed as IV ⇒ B → IV.

Case C (Vitamin B₆): Pyridoxine is listed as I ⇒ C → I.

Case D (Vitamin C): Ascorbic acid is listed as II ⇒ D → II.

Collecting all matches: A - III, B - IV, C - I, D - II.

This exact combination corresponds to Option C.

Hence the correct answer is:
Option C which is: A-III, B-IV, C-I, D-II.
