D. Tectona grandis

Answer

To determine which plant is found in the mangrove zone, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Mangrove Zone**: The mangrove zone is a coastal ecosystem characterized by salt-tolerant trees and shrubs that thrive in intertidal areas.

2. **Identify the Options**: The options provided are:
- A. Rhizophora
- B. Acacia
- C. Pinus
- D. Tectona grandis

3. **Analyze Each Option**:
- **Rhizophora**: This is a genus of tropical mangrove trees. It is known for its ability to grow in saline environments and is often referred to as a "true mangrove." The most notable species within this genus is the red mangrove.
- **Acacia**: Generally found in dry regions and not specifically associated with mangrove ecosystems.
- **Pinus**: This is a genus of coniferous trees commonly found in temperate regions, not in mangrove zones.
- **Tectona grandis**: Commonly known as teak, this tree is found in tropical deciduous forests and does not thrive in mangrove habitats.

4. **Conclusion**: Based on the analysis, Rhizophora is the only plant listed that is specifically adapted to the mangrove zone. It has specialized structures, such as aerial prop roots, that allow it to thrive in the intertidal zone.

5. **Final Answer**: The plant found in the mangrove zone is **Rhizophora** (Option A).
