Assertion : Copper and aluminium are used to make electric wires.
Reason : Copper and aluminium are good conductors of electricity.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Explanation

To analyze the assertion and reason provided in the question, we can break it down step by step:

### Step 1: Understanding the Assertion
The assertion states that "Copper and aluminium are used to make electric wires."
- **Explanation**: This is true because both copper and aluminium are widely used materials in the electrical industry for wiring due to their properties.

### Step 2: Understanding the Reason
The reason given is that "Copper and aluminium are good conductors of electricity."
- **Explanation**: This is also true. Copper and aluminium have high electrical conductivity, which means they allow electric current to flow through them easily.

### Step 3: Linking Assertion and Reason
Now, we need to connect the assertion with the reason:
- The reason explains why the assertion is true. Since copper and aluminium are good conductors of electricity, they are suitable materials for making electric wires.

### Step 4: Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, we can conclude that:
- **Final Answer**: Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
