Which is a polymer of three different monomers?

Options

A. ABS
B. SBR
C. NBR
D. Nylon-2,6

Explanation

To determine which polymer is made from three different monomers, we can analyze the given options one by one.

### Step-by-Step Solution:

1. **Identify the Options**: We have four options to consider:
- A) ABS (Acrylonitrile Butadiene Styrene)
- B) SBR (Styrene Butadiene Rubber)
- C) NBR (Nitrile Butadiene Rubber)
- D) Nylon 2, Nylon 6

2. **Analyze Option A: ABS**:
- ABS is composed of three different monomers:
- Acrylonitrile
- Butadiene
- Styrene
- Since it has three distinct monomers, this option is a candidate.

3. **Analyze Option B: SBR**:
- SBR is made from two monomers:
- Styrene
- Butadiene
- Therefore, this option does not meet the criteria as it only has two monomers.

4. **Analyze Option C: NBR**:
- NBR consists of two monomers:
- Acrylonitrile
- Butadiene
- This option also does not meet the criteria since it has only two monomers.

5. **Analyze Option D: Nylon 2, Nylon 6**:
- Nylon 2, Nylon 6 is a polyamide made from two monomers:
- Glycine
- Aminocaproic Acid
- Thus, this option is incorrect as it has only two monomers.

6. **Conclusion**:
- After analyzing all options, we find that only **Option A (ABS)** is the polymer that is made from three different monomers.

### Final Answer:
The polymer that is made from three different monomers is **ABS (Acrylonitrile Butadiene Styrene)**.
