Body cavity of Earthworm is

Options

A. Schizocoel
B. Enterocoel
C. Pseudocoel
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Body Cavities**: The body cavity in animals is an important feature that can be classified into different types based on their formation and structure. The main types of body cavities include coelom, pseudocoelom, and acoelom.

2. **Identifying the Types**:
- **Coelom**: A true body cavity that is completely lined by mesoderm.
- **Pseudocoelom**: A body cavity that is not completely lined by mesoderm; it is a false cavity.
- **Enterocoel**: A body cavity formed from the gut wall (endoderm).
- **None of these**: An option indicating that none of the above classifications apply.

3. **Focusing on Earthworms**: Earthworms belong to the phylum Annelida. They possess a specific type of body cavity known as a coelom.

4. **Identifying the Correct Type**: In the case of earthworms, the body cavity is specifically referred to as a **"scoelom"** (or coelom). It is formed by the splitting of the mesoderm during embryonic development.

5. **Eliminating Incorrect Options**:
- **Enterocoel**: This type of body cavity is not found in earthworms as it is formed from the endoderm, which does not apply here.
- **Pseudocoel**: This is a false body cavity and is not applicable to earthworms, which have a true coelom.

6. **Conclusion**: Therefore, the correct answer to the question about the body cavity of earthworms is **"coelom"** (or "scoelom").

**Final Answer**: The body cavity of the Earthworm is a **coelom**.
