Match the column :
`{:(,"Column I",,"Column II"),(A.,"Acidic",1.,"Valine"),(B.,"Basic",2.,"Lysine"),(C.,"Neural",3,"Glutamic acid"),(D.,"Aromatic",4.,"Phenylalanine"):}`

Options

A. A - 3, B - 2 , C - 1 , D - 4
B. A - 2, B - 3 , C - 4 , D - 1
C. A - 4, B - 1 , C - 2 , D - 3
D. A - 1, B - 2 , C - 3 , D - 4

Answer

To solve the question of matching the columns, we will analyze each term in Column I and find the corresponding amino acid from Column II based on their characteristics.

### Step-by-Step Solution:

1. **Identify the Characteristics of Amino Acids:**
- **Acidic:** Amino acids that have an additional carboxyl group (-COOH) in their structure, making them acidic.
- **Basic:** Amino acids that contain an extra amino group (-NH2), which makes them basic.
- **Neutral:** Amino acids that do not have a charge at physiological pH.
- **Aromatic:** Amino acids that have an aromatic ring in their structure.

2. **Match Each Characteristic with the Correct Amino Acid:**
- **Valine:** This is a neutral amino acid. It does not have any charged groups and is classified as neutral.
- **Lysine:** This amino acid has an extra amino group, making it basic.
- **Glutamic Acid:** This amino acid has an additional carboxyl group, making it acidic.
- **Phenylalanine:** This amino acid contains an aromatic ring, classifying it as aromatic.

3. **Create the Matches:**
- **A. Acidic:** Matches with **3. Glutamic Acid**
- **B. Basic:** Matches with **2. Lysine**
- **C. Neutral:** Matches with **1. Valine**
- **D. Aromatic:** Matches with **4. Phenylalanine**

4. **Final Matching:**
- A (Acidic) → 3 (Glutamic Acid)
- B (Basic) → 2 (Lysine)
- C (Neutral) → 1 (Valine)
- D (Aromatic) → 4 (Phenylalanine)

### Conclusion:
The correct matches are:
- A → 3
- B → 2
- C → 1
- D → 4
