Which of the following is biodegradable polymer?

Options

A. PHBV
B. Nylon-6
C. Polyethene
D. Nylon-6,10

Answer

To determine which of the following is a biodegradable polymer, we will analyze the options provided and identify the one that fits the criteria of being biodegradable.

### Step-by-Step Solution:

1. **Understanding Biodegradable Polymers**:
- Biodegradable polymers are natural polymers that can be broken down by the action of living organisms, usually bacteria, into natural byproducts such as carbon dioxide (CO2), nitrogen (N2), water, and inorganic salts.

2. **Reviewing the Options**:
- The options given are:
- A) PHBV
- B) Nylon 6
- C) Polyethylene
- D) Nylon 6 Stain

3. **Identifying Synthetic vs. Natural Polymers**:
- Among the options, Nylon 6, Polyethylene, and Nylon 6 Stain are synthetic polymers. They are created through chemical processes in laboratories and do not readily decompose in the environment.
- PHBV (Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)) is a natural polymer produced by bacteria and is known for its biodegradable properties.

4. **Conclusion**:
- Since PHBV is a natural polymer that can be broken down by bacterial action, it is classified as a biodegradable polymer. The other options, being synthetic, do not possess this characteristic.

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