Assertion (A): Copper is used to make electric wires.
Reason (R): Copper has very low electrical resistance.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false.
D. A is false and R is true.

Explanation

To analyze the assertion and reason provided in the question, we can break it down into a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Copper is used to make electric wires."
- This is true because copper is one of the most commonly used materials for electrical wiring.

2. **Understanding the Reason (R)**:
- The reason states that "Copper has very low electrical resistance."
- This is also true. Copper is known for its excellent electrical conductivity, which means it has low resistance.

3. **Relationship Between Conductance and Resistance**:
- Conductance (G) and resistance (R) are inversely related. This means that if a material has high conductance, it will have low resistance.
- Copper has high conductance, which explains its low resistance.

4. **Additional Properties of Copper**:
- Apart from low resistance, copper is also ductile, which means it can be drawn into wires easily.
- Copper is relatively inexpensive compared to other good conductors like silver, making it a practical choice for electrical wiring.

5. **Conclusion**:
- Since both the assertion and the reason are true, and the reason correctly explains why the assertion is true, we conclude that both statements are valid.

### Final Answer:
- Both Assertion (A) and Reason (R) are true, and R is the correct explanation for A.
