Options

A. 1
B. 2
C. 5
D. 8

Explanation

To determine how many keepers a horseshoe magnet needs for its storage, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Horseshoe Magnet**: A horseshoe magnet has two poles: a North Pole and a South Pole. These poles are the areas where the magnetic force is strongest.

2. **Purpose of Keepers**: Keepers are soft iron pieces placed across the poles of a magnet when it is not in use. They help to maintain the magnet's strength by providing a closed magnetic circuit, which reduces the loss of magnetism.

3. **Identifying the Number of Keepers Needed**: For a horseshoe magnet, only one keeper is necessary. This keeper is placed across the North and South poles of the magnet.

4. **Placement of the Keeper**: The keeper is positioned in such a way that it connects the two poles, allowing the magnetic field to flow through it, which helps in preserving the magnet's strength.

5. **Conclusion**: Therefore, the answer to the question is that a horseshoe magnet needs **one keeper** for its storage.

### Final Answer:
A horseshoe magnet needs **one keeper** for its storage.
