Concept:
Vitamins are essential nutrients required for proper growth, metabolism, and maintenance of health.
Each vitamin has a scientific or chemical name.
Step 1: Identify the scientific name of Vitamin A.
Vitamin A is scientifically known as:
\[
\text{Retinol}
\]
Thus:
\[
A \rightarrow II
\]
Step 2: Identify the scientific name of Vitamin D.
Vitamin D is scientifically known as:
\[
\text{Calciferol}
\]
Thus:
\[
B \rightarrow III
\]
Step 3: Identify the scientific name of Vitamin E.
Vitamin E is scientifically known as:
\[
\text{Tocoferol}
\]
Thus:
\[
C \rightarrow I
\]
Step 4: Identify the scientific name of Vitamin C.
Vitamin C is scientifically known as:
\[
\text{Ascorbic Acid}
\]
Thus:
\[
D \rightarrow IV
\]
Step 5: Write the complete matching.
The correct matching becomes:
\[
A-II,\; B-III,\; C-I,\; D-IV
\]
Step 6: Conclusion.
Hence, the correct answer is:
\[
\boxed{A\text{-}II,\; B\text{-}III,\; C\text{-}I,\; D\text{-}IV}
\]
