Which of the following is a biodegradable polymer?

Options

A. Cellulose
B. Polythene
C. Polyvinyl chloride
D. Nylon-6,10

Answer

To determine which of the following is a biodegradable polymer, we need to analyze each option based on its origin and properties.

### Step-by-Step Solution:

1. **Understanding Biodegradable Polymers**:
- Biodegradable polymers are those that can be broken down by microorganisms in the environment, making them less harmful to nature.

2. **Analyzing the Options**:
- **Cellulose**: This is a natural polymer derived from plant cell walls. It is biodegradable because it can be decomposed by bacteria and other microorganisms.
- **Polythene (Polyethylene)**: This is a synthetic polymer made from the polymerization of ethylene. It is not biodegradable as it does not decompose easily in the environment.
- **Polyvinyl Chloride (PVC)**: This is another synthetic polymer made from vinyl chloride. It is also not biodegradable and poses environmental hazards.
- **Nylon 610**: This is a synthetic fiber made from the combination of nylon 6 and nylon 10. Like the others, it is not biodegradable.

3. **Conclusion**:
- Among the options given, only **cellulose** is a biodegradable polymer. The other options (polythene, polyvinyl chloride, and nylon 610) are synthetic and do not decompose easily.

### Final Answer:
The biodegradable polymer among the options is **Cellulose**.
