Styrene-butadiene is a

Options

A. Synthetic rubber
B. Natural rubber
C. Biodegradable plastic
D. Recycled plastic

Answer

**Step-by-Step Solution:**

1. **Understanding Styrene-Butadiene**: The question asks about styrene-butadiene and its classification. Styrene-butadiene is a type of polymer.

2. **Identifying the Options**: The options provided are:
- Synthetic rubber
- Natural rubber
- Biodegradable plastic
- Recycled plastic

3. **Analyzing Each Option**:
- **Synthetic Rubber**: Styrene-butadiene is known to be a synthetic rubber. It is created through the polymerization of styrene and butadiene monomers.
- **Natural Rubber**: This is primarily polyisoprene, which is derived from natural sources like rubber trees. Styrene-butadiene does not fall under this category.
- **Biodegradable Plastic**: This refers to plastics that can decompose naturally. Styrene-butadiene does not fit this definition.
- **Recycled Plastic**: This is plastic that has been processed to be reused. Styrene-butadiene is not classified as recycled plastic.

4. **Conclusion**: Based on the analysis, the correct classification for styrene-butadiene is "synthetic rubber".

5. **Final Answer**: Therefore, the answer to the question is that styrene-butadiene is a **synthetic rubber**.
