Step-by-Step Solution

To determine the correct matching between the amino acids in List-I and their corresponding one-letter symbols and nutritional classifications (Essential or Non-essential) in List-II, we analyze each amino acid as follows:

  1. Arginine (A):

    • One-letter symbol: R\text{R}
    • Type: Essential amino acid
    • Match: A→II\text{A} \rightarrow \text{II} (R / Essential\text{R / Essential})

  2. Aspartic acid (B):

    • One-letter symbol: D\text{D}
    • Type: Non-essential amino acid
    • Match: B→I\text{B} \rightarrow \text{I} (D / Non-essential\text{D / Non-essential})

  3. Lysine (C):

    • One-letter symbol: K\text{K}
    • Type: Essential amino acid
    • Match: C→IV\text{C} \rightarrow \text{IV} (K / Essential\text{K / Essential})

  4. Glutamic acid (D):

    • One-letter symbol: E\text{E}
    • Type: Non-essential amino acid
    • Match: D→III\text{D} \rightarrow \text{III} (E / Non-essential\text{E / Non-essential})

Combining all these correct pairs: A-II, B-I, C-IV, D-III\text{A-II, B-I, C-IV, D-III}

This corresponds to Option A.
