Pneumatophores are found in

Options

A. Orchid
B. Piper
C. Ficus
D. Rhizophora

Answer

**Step-by-Step Solution:**

1. **Understanding Pneumatophores**: Pneumatophores are specialized aerial roots that help in respiration. They are typically found in plants that grow in waterlogged or saline environments.

2. **Identifying the Conditions**: These roots are commonly associated with halophytic plants, which are adapted to thrive in saline conditions, such as swamps or coastal areas.

3. **Analyzing the Options**:
- **Orchid**: Orchids are not typically associated with saline environments and do not have pneumatophores.
- **Viper**: This option is not relevant as it refers to a type of snake, not a plant.
- **Ficus**: While some Ficus species may have aerial roots, they are not primarily known for pneumatophores.
- **Rhizophora**: This is a genus of mangrove trees that are well-known for having pneumatophores, which help them breathe in oxygen-rich air above the waterlogged soil.

4. **Conclusion**: Based on the analysis, the correct answer is **Rhizophora**, as it is a halophyte that possesses pneumatophores.

**Final Answer**: Pneumatophores are found in **Rhizophora**.
