Which of these is a non-biodegradable material?

Options

A. Wood
B. Plastics
C. Fruit peels
D. Dried leaves

Explanation

To determine which of the given materials is non-biodegradable, we need to understand the definition of biodegradable and non-biodegradable materials.

### Step-by-Step Solution:

1. **Understand the Definition**:
- **Biodegradable materials** are those that can be broken down by natural processes, such as decomposition by microorganisms. Examples include food waste, paper, and wood.
- **Non-biodegradable materials** are those that do not break down naturally and can persist in the environment for a long time. Examples include plastics, metals, and certain synthetic materials.

2. **Analyze the Options**:
- Let's consider the common materials that could be presented as options:
- Plastic
- Wood
- Fruit peels
- Diet (assuming this refers to food items)

3. **Evaluate Each Option**:
- **Plastic**: This is a synthetic material that does not decompose easily and can remain in the environment for hundreds of years. Therefore, it is classified as non-biodegradable.
- **Wood**: This is a natural material that can decompose over time, making it biodegradable.
- **Fruit peels**: These are organic waste that can be broken down by microorganisms, hence they are biodegradable.
- **Diet (food items)**: Most food items are also organic and can decompose, thus they are biodegradable.

4. **Conclusion**:
- Based on the analysis, the only non-biodegradable material among the options is **Plastic**.

### Final Answer:
The non-biodegradable material is **Plastic**.
