Match the column :
`{:(,"Polymer",,"Linkage",),((i),"Terylene",(a),"Glycosidic linkage",),((ii),"Cellulose",(b),"Ester linkage",),((iii),"Protein",(c ),"Phosphodiester linkage",),((iv),"RNA",(d),"Amide linkage ",):}`

Options

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

Answer

To solve the matching question, we will identify the correct linkage for each polymer listed. The polymers and their respective linkages are:

1. **Terylene**
2. **Cellulose**
3. **Protein**
4. **RNA**

### Step-by-Step Solution:

1. **Identify the linkage for Terylene:**
- Terylene, also known as Dacron, is a polyester. The linkage present in Terylene is the **Ester linkage**.
- **Match:** Terylene → (b) Ester linkage

2. **Identify the linkage for Cellulose:**
- Cellulose is a polysaccharide made of glucose units. The linkage between glucose units in cellulose is known as the **Glycosidic linkage**.
- **Match:** Cellulose → (a) Glycosidic linkage

3. **Identify the linkage for Protein:**
- Proteins are made up of amino acids linked together by **Peptide bonds**, which are also referred to as **Amide linkages**.
- **Match:** Protein → (d) Amide linkage

4. **Identify the linkage for RNA:**
- RNA is a nucleic acid that has a backbone formed by **Phosphodiester linkages** between the sugar and phosphate groups.
- **Match:** RNA → (c) Phosphodiester linkage

### Final Matches:
- Terylene → (b) Ester linkage
- Cellulose → (a) Glycosidic linkage
- Protein → (d) Amide linkage
- RNA → (c) Phosphodiester linkage

Thus, the final answer is:
- (i) Terylene → (b)
- (ii) Cellulose → (a)
- (iii) Protein → (d)
- (iv) RNA → (c)
