Echinodermate possesses
(a) Pseudocoelom
(b) Schizocoelom
(c) Enterocoelom
(d) None of the above

Options

A. Pseudocoelom
B. Schizocoelom
C. Enterocoelom
D. None of the above.

Answer

To answer the question regarding what type of coelom Echinodermata possesses, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Echinodermata**: Echinoderms are marine animals that belong to the phylum Echinodermata. They include organisms such as starfish, sea urchins, and sea cucumbers.

2. **Identifying Coelom Types**: The question provides four options regarding the type of coelom:
- (a) Pseudocoelom
- (b) Schizocoelom
- (c) Enterocoelom
- (d) None of the above

3. **Analyzing the Coelom**:
- **Pseudocoelom**: This is a body cavity that is not completely lined with mesoderm. Echinoderms do not possess a pseudocoelom; they have a true coelom.
- **Schizocoelom**: This type of coelom is formed by the splitting of mesodermal tissue. Echinoderms do not have a schizocoelom.
- **Enterocoelom**: This is a coelom that forms from the outpocketing of the archenteron (the primitive gut). Echinoderms are classified as deuterostomes, and they develop their coelom through this method.

4. **Conclusion**: Since Echinoderms possess an enterocoelom, the correct answer is:
- **(c) Enterocoelom**

### Final Answer:
Echinodermata possesses **(c) Enterocoelom**.
