Which of the following is not a man made polymer ?

Options

A. nylon
B. polyethen
C. teflon
D. wool

Answer

To determine which of the following is not a man-made polymer, we need to identify the nature of each option provided.

### Step-by-Step Solution:

1. **Understand the Definition of Man-Made Polymers**:
- Man-made polymers are synthetic materials created by scientists and engineers through chemical processes. Examples include nylon, polythene, and Teflon.

2. **List the Given Options**:
- The options typically include various substances. For this example, let's assume the options are:
- A) Nylon
- B) Polythene
- C) Teflon
- D) Wool

3. **Identify Each Option**:
- **Nylon**: This is a synthetic polymer made from petrochemicals. It is a man-made polymer.
- **Polythene**: Also a synthetic polymer, commonly used in plastic bags and containers. It is man-made.
- **Teflon**: This is another synthetic polymer known for its non-stick properties, used in cookware. It is man-made.
- **Wool**: This is a natural polymer made from the fleece of sheep. It is not man-made.

4. **Conclusion**:
- Among the options provided, **Wool** is the only one that is not a man-made polymer. Therefore, the answer to the question is **Wool**.

### Final Answer:
Wool is not a man-made polymer.
