D. Fungia

Answer

To determine which organism does not belong to the class Anthozoa, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification**:
- Anthozoa is a class under the Phylum Cnidaria (not Neidheria, which seems to be a typo).
- Phylum Cnidaria consists of four main classes: Cubozoa, Scyphozoa, Hydrozoa, and Anthozoa.

2. **Identify Characteristics of Anthozoa**:
- Organisms in the class Anthozoa possess tentacles and a gastrovascular cavity.
- Examples of organisms in this class include corals and sea anemones.

3. **Examine the Options**:
- We need to look at the options provided and identify which one does not have the characteristics of Anthozoa.

4. **Identify Ephyra**:
- Ephyra is known as the larval form of Aurelia, which is commonly recognized as a jellyfish.
- Jellyfish belong to the class Scyphozoa.

5. **Conclusion**:
- Since Ephyra is a larval stage of a jellyfish (Aurelia) and belongs to the class Scyphozoa, it does not belong to the class Anthozoa.

### Final Answer:
Ephyra does not belong to the class Anthozoa.
