Which of the following is/are conductors?

Options

A. Copper
B. Aluminum
C. Glass
D. Wood

Answer

To determine which of the given options are conductors, we need to understand what conductors are and identify the materials listed in the options.

### Step-by-Step Solution:

1. **Define Conductors**:
- Conductors are materials that allow the flow of electric current. They have a high number of free electrons that can move easily through the material.

2. **Identify Common Conductors**:
- Common examples of conductors include metals such as copper, aluminum, silver, and gold. These materials have a high density of free electrons.

3. **Analyze the Given Materials**:
- The options provided are:
- Copper
- Aluminum
- Glass
- Wood
- Now, we will classify each material:
- **Copper**: This is a metal and is a good conductor of electricity.
- **Aluminum**: This is also a metal and is a good conductor of electricity.
- **Glass**: This is a non-metal and is an insulator, meaning it does not conduct electricity well.
- **Wood**: This is also a non-metal and is generally considered an insulator.

4. **Conclusion**:
- From the analysis, the conductors among the given options are:
- Copper (conductor)
- Aluminum (conductor)
- Therefore, the answer is that the conductors are Copper and Aluminum.

### Final Answer:
- The conductors from the options provided are Copper and Aluminum.
