Name the synthetic fibre which is prepared from coal, water and air.

Options

A. Nylon
B. Rayon
C. Polyester
D. None of these

Answer

To answer the question, "Name the synthetic fibre which is prepared from coal, water, and air," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components**: The question specifies that the synthetic fibre is made from coal, water, and air. We need to identify which synthetic fibre fits this description.

2. **Identify Synthetic Fibres**: Common synthetic fibres include nylon, polyester, and acrylic. We need to determine which of these is derived from the mentioned components.

3. **Research the Production Process**:
- **Nylon**: Nylon is a synthetic polymer that is produced through a chemical process involving coal, water, and air. It is made from the polymerization of amides, which can be derived from coal.
- **Polyester**: Polyester is primarily made from petroleum products and does not fit the criteria of being made from coal, water, and air.
- **Acrylic**: Acrylic fibres are made from acrylonitrile, which is derived from petroleum, not coal.

4. **Conclusion**: Based on the analysis, the synthetic fibre that is prepared from coal, water, and air is **Nylon**.

### Final Answer:
The synthetic fibre which is prepared from coal, water, and air is **Nylon**.
