Coelom of urochordate is

Options

A. Schizocoel
B. Absent
C. Enterocoel
D. Segmented

Answer

### Step-by-Step Solution:

1. **Understanding Urochordates**: Urochordates, also known as tunicates, are marine animals that belong to the phylum Chordata. They exhibit some characteristics of chordates, particularly during their larval stage.

2. **Coelom Definition**: A coelom is a fluid-filled body cavity that is completely lined by mesoderm. It serves as a space for the development and organization of internal organs.

3. **Types of Coelom**: There are different types of coeloms:
- **Schizocoelom**: Formed by the splitting of the mesodermal mass.
- **Enterocoelom**: Formed from the outpouching of the embryonic gut (archenteron).
- **Segmented Coelom**: Refers to a coelom that is divided into segments.

4. **Coelom in Urochordates**: Urochordates are unique among chordates because they do not possess a true coelom. While they have the three embryonic layers (ectoderm, mesoderm, and endoderm), the coelom is absent.

5. **Conclusion**: Therefore, the correct answer to the question regarding the coelom of urochordates is that it is **absent**.
