Hydra and yeast is an example of:

Options

A. Budding
B. Fertilisation
C. Fission
D. Cloning

Explanation

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question asks about Hydra and yeast. Hydra is a multicellular organism, while yeast is a unicellular fungus.

2. **Understand Their Reproductive Methods**: Both Hydra and yeast reproduce asexually. Asexual reproduction is a process where a single organism can reproduce without the involvement of gametes (sperm and egg).

3. **Focus on the Type of Asexual Reproduction**: The options provided are budding, fertilization, fission, and cloning. We need to determine which of these is applicable to both Hydra and yeast.

4. **Define Budding**: Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. This bud eventually detaches to become a new individual.

5. **Examine Hydra's Reproduction**: In Hydra, a small bud forms on the body of the parent Hydra. This bud grows and eventually detaches to become a new Hydra.

6. **Examine Yeast's Reproduction**: In yeast, a similar process occurs where a small bud forms on the parent yeast cell. This bud grows and eventually separates to form a new yeast cell.

7. **Conclusion**: Since both Hydra and yeast reproduce through the process of budding, the correct answer to the question is "budding".

**Final Answer**: Hydra and yeast are examples of budding.
