Identify the wrong pair from the following.

Options

A. Euglena - Binary fission
B. Yeast - Budding
C. Spirogyra - Fragmentation
D. Hydra - Multiple fission

Explanation

To identify the wrong pair from the options given, we need to analyze each pair carefully.

1. **Euclid and Binary Fission**:
- Binary fission is a method of asexual reproduction where a single organism divides into two parts, each of which can grow into a new organism. This is indeed the correct method of reproduction for Euclid (which seems to be a typographical error and should refer to "Euglena"). Therefore, this pair is correct.

2. **Yeast and Budding**:
- Yeast reproduces asexually through a process called budding, where a new organism develops from an outgrowth or bud on the parent organism. This description matches the reproductive method of yeast. Thus, this pair is also correct.

3. **Spirogyra and Fragmentation**:
- Spirogyra reproduces asexually through fragmentation, where the filamentous structure breaks into fragments, and each fragment can grow into a new individual. This is an accurate description, making this pair correct as well.

4. **Hydra and Multiple Fission**:
- Hydra primarily reproduces asexually through budding, not multiple fission. In budding, a new individual develops from a bud on the parent organism. Therefore, this pair is incorrect.

Based on the analysis, the wrong pair is **Hydra and Multiple Fission**.

### Summary of the Solution:
- The wrong pair is **Hydra and Multiple Fission** because Hydra reproduces through budding, not multiple fission.
