To match the deficiency diseases given in List-I with their corresponding vitamins in List-II, we recall the standard vitamins and their associated deficiency disorders:

1. Scurvy:

   • Cause: Deficiency of Vitamin C.
   • Chemical Name: Ascorbic Acid.
   • Match: $\text{A} \rightarrow \text{III}$

2. Convulsions:

   • Cause: Deficiency of Vitamin $\text{B}_6$.
   • Chemical Name: Pyridoxine.
   • Match: $\text{B} \rightarrow \text{I}$

3. Cheilosis:

   • Cause: Deficiency of Vitamin $\text{B}_2$ (characterized by inflammation and cracking of the skin at the corners of the mouth).
   • Chemical Name: Riboflavin.
   • Match: $\text{C} \rightarrow \text{IV}$

4. Xerophthalmia:

   • Cause: Deficiency of Vitamin A (characterized by hardening of the cornea of the eye).
   • Chemical Name: Vitamin A.

Combining these matches, we get: $\text{A-III, B-I, C-IV, D-II}$

This corresponds to the correct option C.
