Which of the following is/are an angiospermic hydrophyte ?

Options

A. hydrilla
B. Vallisneria
C. Zizyphus
D. Both A and B

Answer

To determine which of the following options are angiospermic hydrophytes, we need to analyze each option provided in the question.

### Step-by-step Solution:

1. **Understanding Angiospermic Hydrophytes**:
- Angiospermic hydrophytes are flowering plants that have adapted to live in aquatic environments. They are characterized by their ability to thrive in water and have specific adaptations for such habitats.

2. **Analyzing the Options**:
- The options given are:
- A) Hydrilla
- B) Valisneria
- C) Ziziphus
- D) Both A and B

3. **Identifying Hydrophytes**:
- **Hydrilla**: This is an aquatic plant that grows submerged in water. It is indeed an angiosperm and is adapted to living in aquatic environments.
- **Valisneria**: This is also an aquatic plant, commonly found in freshwater bodies. It is a flowering plant and fits the definition of an angiospermic hydrophyte.
- **Ziziphus**: This plant is not aquatic; it is a xerophyte, which means it is adapted to dry environments and does not thrive in water.

4. **Conclusion**:
- From the analysis, both Hydrilla and Valisneria are angiospermic hydrophytes. Ziziphus is not an angiospermic hydrophyte. Therefore, the correct answer is option D) Both A and B.

### Final Answer:
The correct options that are angiospermic hydrophytes are **Both A and B (Hydrilla and Valisneria)**.
