Transmission wires are made by

Options

A. plastic
B. rubber
C. jute
D. aluminium

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what materials are used to make transmission wires. Transmission wires are essential components in electrical systems, as they carry electric current from one point to another.

2. **Identifying the Options**: The given options are:
- Plastic
- Rubber
- Jute
- Aluminium

3. **Analyzing the Properties of Each Material**:
- **Plastic**: This is an insulator, meaning it does not allow electric current to flow through it.
- **Rubber**: Similar to plastic, rubber is also an insulator and does not conduct electricity.
- **Jute**: Jute is a natural fiber and is not a conductor of electricity; it is also an insulator.
- **Aluminium**: Aluminium is a metal and is known to be a good conductor of electricity.

4. **Conclusion**: Since transmission wires need to conduct electricity effectively, they must be made from materials that are good conductors. Among the options provided, only aluminium is a conductor that allows electric current to flow.

5. **Final Answer**: Therefore, transmission wires are made of **Aluminium**.
