Which of the following are made using chemical compounds of petroleum origin (petrochemicals)

Options

A. Silk
B. Cotton
C. Rayon
D. Nylon, polyester and acrylic

Answer

To determine which of the following options are made using chemical compounds of petroleum origin (petrochemicals), we need to analyze each option provided.

1. **Identify the options**: The question implies that there are multiple options to choose from. We will evaluate each one to see if they are made from petrochemicals.

2. **Evaluate each option**:
- **Option 1: Silk** - Silk is a natural fiber obtained from the cocoon of the silkworm. Since it is derived from a living organism and not synthesized from petrochemicals, this option is incorrect.
- **Option 2: Cotton** - Cotton is also a natural fiber, derived from the cotton plant. Like silk, it is not made from petrochemicals, so this option is incorrect.
- **Option 3: Rayon** - Rayon is a semi-synthetic fiber made from cellulose, which is derived from wood pulp. Although it is processed, it is not made from petrochemicals, making this option incorrect as well.
- **Option 4: Polyester, Acrylic, Nylon** - All of these fibers are synthetic and are made from chemical compounds derived from petroleum. Therefore, this option is correct.

3. **Conclusion**: The only option that consists of materials made from chemical compounds of petroleum origin is **Option 4: Polyester, Acrylic, Nylon**.

### Final Answer:
The correct answer is **Option 4: Polyester, Acrylic, Nylon**.
