D. Chalina.

Answer

**Step-by-Step Solution:**

1. **Understanding Moonga**: Moonga is a type of jewelry stone, specifically known for its vibrant color. It is essential to identify the source of this stone to answer the question correctly.

2. **Identifying the Source**: Moonga is obtained from corals, particularly the red coral. The scientific name for red coral is Corallium.

3. **Characteristics of Red Coral**: The red coral is known for its exoskeleton, which has a red or pink color. This characteristic makes it valuable for jewelry.

4. **Classification of Corals**: Corals belong to the kingdom Animalia and are classified under the phylum Cnidaria. Within this phylum, red corals are part of the class Anthozoa.

5. **Life Forms of Corals**: Corals can exist in two life forms: the polyp and the medusa. The polyp is the sessile (non-moving) form, while the medusa is the motile form. Moonga is obtained from the polyp stage of corals.

6. **Evaluating Other Options**:
- Heliopora (blue coral) is not the source of Moonga.
- Euplectella (Venus flower basket) is a sponge and does not produce Moonga.
- Celina (another type of sponge) is also not related to Moonga.

7. **Conclusion**: The only correct source of Moonga is Corallium, which is the red coral.

**Final Answer**: Moonga is obtained from Corallium (red coral).
