Consider the following statements
(i) for a permanent magnet the area of a hysteresis loop is allowed to be large
(ii) Coercivity o the material in permanent magnets should be small.
Which of the following statements is/are true?

Options

A. (i) but not (ii)
B. (ii) but not (i)
C. Both (i) and (ii)
D. Neither (i) nor (ii)

Explanation

To solve the problem, we need to analyze the two statements provided about permanent magnets and determine their validity.

### Step-by-Step Solution:

1. **Understanding Hysteresis Loop**:
- The hysteresis loop represents the relationship between the magnetic field strength (H) and the magnetic flux density (B) in a magnetic material. The area of this loop indicates energy loss due to magnetization and demagnetization processes.

2. **Analyzing Statement (i)**:
- The first statement claims that "for a permanent magnet, the area of a hysteresis loop is allowed to be large."
- A large area in the hysteresis loop indicates that the material has high energy losses during magnetization and demagnetization. However, for a good permanent magnet, we want the area to be large to ensure that the material can retain a significant amount of magnetic energy after the external magnetic field is removed. Thus, this statement is **true**.

3. **Analyzing Statement (ii)**:
- The second statement claims that "coercivity of the material in permanent magnets should be small."
- Coercivity is the measure of the resistance of a magnetic material to changes in magnetization. For permanent magnets, we want high coercivity so that the magnet can maintain its magnetization against external demagnetizing influences. Therefore, this statement is **false**.

4. **Conclusion**:
- Based on the analysis, we conclude that:
- Statement (i) is true.
- Statement (ii) is false.
- Therefore, the correct answer is that only the first statement is true.

### Final Answer:
- **Only statement (i) is true.**
