Which one is a synthetic polymer?

Options

A. Starch
B. Silk
C. Protein
D. Neoprene

Answer

To determine which of the given options is a synthetic polymer, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) Starch
- B) Silk
- C) Proteins
- D) Neoprene

2. **Define Synthetic Polymers**: Synthetic polymers are man-made polymers created through chemical processes, typically involving the polymerization of monomers.

3. **Analyze Each Option**:
- **Starch**: This is a natural polymer made from glucose units and is commonly found in plants.
- **Silk**: This is a natural protein fiber produced by silkworms and is also a natural polymer.
- **Proteins**: These are natural polymers made up of amino acids and are found in all living organisms.
- **Neoprene**: This is a synthetic polymer, specifically a type of synthetic rubber, created from the polymerization of chloroprene.

4. **Conclusion**: Based on the analysis, the only synthetic polymer among the options is **Neoprene**.

5. **Final Answer**: Therefore, the answer is **Option D: Neoprene**.
