Assertion (A): Safety fuses are made up of materials having a low melting point.
Reason (R): Safety fuses should be resistant to electric current

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

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that safety fuses are made up of materials having a low melting point. This is true because safety fuses are designed to melt and break the circuit when excessive current flows through them.

2. **Understanding the Reason (R)**: The reason states that safety fuses should be resistant to electric current. This statement is misleading. While fuses need to handle normal current without melting, they are not meant to resist excessive current. Instead, they are designed to melt when the current exceeds a certain threshold.

3. **Evaluating the Assertion and Reason**:
- The assertion is correct: Safety fuses do have a low melting point to ensure they can break the circuit under high current conditions.
- The reason is incorrect: Fuses are not designed to resist high current; they are designed to allow normal current to pass and to melt when the current exceeds safe levels.

4. **Conclusion**: Based on the evaluation, the assertion is true, and the reason is false. Therefore, the correct answer is that the assertion is true, and the reason is false.

**Final Answer**: Assertion (A) is true, and Reason (R) is false.
