(i) `-A -A -A-A-A-A-`
(ii) `-A-B-B-A-A-A-B-A-`

Options

A. (i) Homopolymer, (ii) Copolymer
B. (i) Natural polymer (ii) Synthetic polymer
C. (i) Linear polymer , (ii) Branched polmer
D. (i) Fibre , (ii) Elastomer

Answer

To identify the type of polymers given in the question, we will analyze each polymer structure step by step.

### Step 1: Analyze the first polymer structure
The first polymer is represented as `-A -A -A -A -A -A-`.

1. **Identify the monomeric units**:
- In this structure, we can see that the repeating unit is `A`.
- There are no other types of monomeric units present.

2. **Determine the type of polymer**:
- Since the polymer consists of only one type of monomeric unit (A), it is classified as a **homopolymer**.

### Step 2: Analyze the second polymer structure
The second polymer is represented as `-A -B -B -A -A -A -B -A-`.

1. **Identify the monomeric units**:
- In this structure, we can observe two different types of monomeric units: `A` and `B`.
- The polymer consists of both `A` and `B` repeating units.

2. **Determine the type of polymer**:
- Since this polymer contains two different monomeric units (A and B), it is classified as a **copolymer**.

### Final Conclusion
- The first polymer is a **homopolymer**.
- The second polymer is a **copolymer**.

### Summary of the Solution
1. The first polymer `-A -A -A -A -A -A-` is a **homopolymer**.
2. The second polymer `-A -B -B -A -A -A -B -A-` is a **copolymer**.
