Pick the odd one out.
Hydra, Yeast, Amoeba

Explanation

### Step-by-Step Solution:

1. **Identify the Organisms**: The three organisms mentioned are Hydra, Yeast, and Amoeba.

2. **Understand Their Reproductive Methods**:
- **Hydra**: Reproduces asexually through a process called budding. In this process, a small outgrowth (bud) forms on the parent organism, grows, and eventually detaches to become a new individual.
- **Yeast**: Also reproduces asexually through budding. Similar to Hydra, a bud forms on the yeast cell, grows, and then separates to form a new yeast cell.
- **Amoeba**: Reproduces asexually through a process called binary fission. In binary fission, the Amoeba cell divides into two identical daughter cells.
