Select the odd one w.r.t.vegetative reproduction in fungi.

Options

A. Gamentangial contact
B. Fragmentation
C. Fission
D. Budding

Answer

To solve the question of selecting the odd one out with respect to vegetative reproduction in fungi, we need to analyze each of the given options:

1. **Gametangial Contact**:
- This process is associated with sexual reproduction in fungi. In gametangial contact, male and female gametes come into contact, leading to fertilization and the formation of zygotes. This is not a method of vegetative reproduction.

2. **Fragmentation**:
- Fragmentation is a method of asexual reproduction where a fungus breaks into fragments, and each fragment can grow into a new individual. This is a form of vegetative reproduction.

3. **Fission**:
- Fission, specifically binary fission, is another method of asexual reproduction where a single organism divides into two or more parts, each of which can develop into a new organism. This is also a form of vegetative reproduction.

4. **Budding**:
- Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. This is also a method of vegetative reproduction.

Now, we can summarize the findings:

- **Gametangial Contact** is the only option that pertains to sexual reproduction, while **Fragmentation**, **Fission**, and **Budding** are all methods of vegetative (asexual) reproduction.

Thus, the odd one out is **Gametangial Contact**.

### Final Answer:
**Gametangial Contact** is the odd one out with respect to vegetative reproduction in fungi.
