C. a-v, b-i, c-iv, d-iii
D. a-ii, b-i, c-v, d-iii

Answer

To solve the matching question, we will analyze each linkage in Column 1 and find the corresponding compound in Column 2.

### Step-by-Step Solution:

1. **Identify the first linkage: Hydrogen bond (I)**
- Hydrogen bonds are weak interactions that occur between complementary bases in DNA. Specifically, Guanine (G) and Cytosine (C) form three hydrogen bonds between them.
- **Match:** I → v (Guanine-Cytosine on opposite strands of DNA)

2. **Identify the second linkage: N-glycosidic linkage (II)**
- N-glycosidic linkages form between a nitrogenous base and a sugar molecule. In DNA, this occurs between adenine (a nitrogenous base) and deoxyribose (a sugar).
- **Match:** II → a (Adenine-deoxyribose)

3. **Identify the third linkage: Phosphodiester bond (III)**
- Phosphodiester bonds link nucleotides together in a polynucleotide chain, forming the backbone of DNA and RNA. This bond occurs between the phosphate group of one nucleotide and the hydroxyl group on the sugar of another nucleotide.
- **Match:** III → iv (Nucleotide-Nucleotide in polynucleotide chain)

4. **Identify the fourth linkage: Peptide bond (IV)**
- Peptide bonds are formed between amino acids. They link the carboxyl group of one amino acid to the amino group of another. In this case, Leucine and Glycine are two amino acids that can be linked by a peptide bond.
- **Match:** IV → iii (Leucine-Glycine)

### Final Matches:
- I → v (Guanine-Cytosine on opposite strands of DNA)
- II → a (Adenine-deoxyribose)
- III → iv (Nucleotide-Nucleotide in polynucleotide chain)
- IV → iii (Leucine-Glycine)

### Correct Option:
The correct option based on the matches is **Option 3**.
