Which of the following is the best matched options ?

Options

A. (i) - (A), (v) - (D), (iii) - (C), (iv) - (B)
B. (i) - (D), (ii) - (C), (iii) - (A), (iv) - (B)
C. (i) - (D), (v) - (D), (iii) - (A), (iv) - (B)
D. (i) - (A), (ii) - (C), (iii) - (D), (iv) - (B)

Explanation

To solve the matching question, we need to pair each item from the left column with the correct item from the right column. Let's analyze each item one by one.

### Step 1: Analyze the First Item - Amino Acids
- Amino acids are the building blocks of proteins.
- Therefore, the correct match for "Amino acids" is **(A) Protein**.

### Step 2: Analyze the Second Item - Thymine
- Thymine is one of the nitrogenous bases found in DNA.
- Therefore, the correct match for "Thymine" is **(C) DNA**.

### Step 3: Analyze the Third Item - Insulin
- Insulin is a type of protein that regulates glucose levels in the blood.
- Therefore, the correct match for "Insulin" is **(A) Protein**.

### Step 4: Analyze the Fourth Item - Phosphodiester Linkage
- Phosphodiester linkage is a type of bond that connects nucleotides in nucleic acids (DNA and RNA).
- Therefore, the correct match for "Phosphodiester linkage" is **(B) Nucleic acid**.

### Step 5: Analyze the Fifth Item - Uracil
- Uracil is a nitrogenous base found in RNA, replacing thymine found in DNA.
- Therefore, the correct match for "Uracil" is **(B) Nucleic acid**.

### Summary of Matches
1. Amino acids - (A) Protein
2. Thymine - (C) DNA
3. Insulin - (A) Protein
4. Phosphodiester linkage - (B) Nucleic acid
5. Uracil - (B) Nucleic acid

### Final Matching
- I: Amino acids - (A) Protein
- II: Thymine - (C) DNA
- III: Insulin - (A) Protein
- IV: Phosphodiester linkage - (B) Nucleic acid
- V: Uracil - (B) Nucleic acid

### Best Matched Option
Based on the analysis, the best matched option is **Option 2**.
