D. Magnetic separation

Answer

To separate the small pebbles from a bag of rice, we can use the method of hand picking. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Mixture**: The mixture consists of rice and small pebbles. The pebbles are larger and can be easily distinguished from the rice.

2. **Choose the Separation Method**: Since the pebbles are larger than the rice grains and can be seen easily, the most effective method to separate them is hand picking.

3. **Perform Hand Picking**:
- Take a handful of the mixture.
- Visually inspect the mixture to locate the pebbles.
- Use your fingers to pick out the pebbles from the rice.
- Place the pebbles aside in a separate container.

4. **Repeat the Process**: Continue this process until all the pebbles are removed from the rice.

5. **Final Check**: Once you believe all the pebbles have been removed, do a final check to ensure that no pebbles are left in the rice.
