B. Grass , Plastic , Banana Peel
C. Wood , Grass , Banana Peel
D. Leather , Glass , Banana Peel.

Answer

To determine which group consists only of biodegradable substances, we need to understand what biodegradable substances are. Biodegradable substances are organic materials that can be broken down by microorganisms into simpler organic or inorganic molecules. Here’s how we can approach the question step by step:

### Step-by-Step Solution:

1. **Define Biodegradable Substances**:
- Biodegradable substances are materials that can be decomposed by bacteria or other biological means. They typically include organic materials like food waste, paper, and certain types of plastics.

2. **Identify Examples of Biodegradable Substances**:
- Common examples include:
- Food scraps (like fruit and vegetable peels)
- Paper products
- Yard waste (like grass clippings and leaves)
- Natural fibers (like cotton and wool)

3. **Identify Non-Biodegradable Substances**:
- Non-biodegradable substances are materials that do not break down easily in the environment. Examples include:
- Plastics
- Glass
- Metals
- Synthetic fibers

4. **Analyze the Given Options**:
- Look at the options provided in the question. We need to find a group that contains only biodegradable substances.
- For example, if the options are:
- Option A: Wood, Grass, Banana Peel
- Option B: Leather, Glass, Banana Peel
- Option C: Plastic, Wood, Banana Peel
- We can see that:
- Option A contains only biodegradable substances (Wood, Grass, Banana Peel).
- Option B contains non-biodegradable glass.
- Option C contains non-biodegradable plastic.

5. **Select the Correct Option**:
- Based on the analysis, the correct answer is the option that contains only biodegradable substances. In this case, it would be Option A: Wood, Grass, Banana Peel.

### Final Answer:
The group of only biodegradable substances is **Option A: Wood, Grass, Banana Peel**.
