Which of the following products can't be decomposed easily?

Options

A. Acrylic
B. Plastic
C. Polythene
D. All of the above

Answer

To determine which of the following products can't be decomposed easily, we need to categorize the products into two main types: biodegradable and non-biodegradable materials.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Biodegradable Products**: These are materials that can be broken down into simpler, usable forms by natural processes, often involving microorganisms like bacteria.
- **Non-Biodegradable Products**: These materials cannot be easily broken down or decomposed by natural processes. They remain in the environment for a long time without changing into usable forms.

2. **Identify the Products**:
- We need to look at the list of products provided in the question. Common examples of non-biodegradable materials include plastics, polythene, and acrylic.

3. **Analyze Each Product**:
- **Acrylic**: A type of plastic that is non-biodegradable.
- **Plastic**: Generally, plastics are non-biodegradable and take hundreds of years to decompose.
- **Polythene**: Another form of plastic that is also non-biodegradable.

4. **Conclusion**:
- Since all the mentioned products (acrylic, plastic, and polythene) fall under the category of non-biodegradable materials, they cannot be decomposed easily. Therefore, the answer to the question is that all of the above products cannot be decomposed easily.

5. **Final Answer**:
- The correct answer is **all of the above** (Option 4).
