Evisceration is characteristic of

Options

A. Cucumaria
B. Echinus
C. Echinoarachhinus
D. Neometra.

Answer

### Step-by-Step Solution:

1. **Understanding Evisceration**: Evisceration is defined as the process of ejecting internal organs from the body. This is a defense mechanism used by certain organisms to protect themselves from predators.

2. **Identifying the Organisms**: The options given are Kukumaria, Kinase, Kino, Arcanus, and Neometra. We need to determine which of these organisms exhibits evisceration.

3. **Analyzing Kukumaria**: Kukumaria, commonly known as sea cucumber, is known for its ability to eject its internal organs as a defense mechanism. This process allows it to escape predators, as the expelled organs can distract or confuse them.

4. **Classifying Kukumaria**: Kukumaria belongs to the class Holothuroidea, which is characterized by this unique ability of evisceration. This class includes various species of sea cucumbers.

5. **Examining Other Options**:
- **Kinase**: This organism does not exhibit evisceration.
- **Kino**: This organism also does not exhibit evisceration.
- **Arcanus**: This organism does not exhibit evisceration.
- **Neometra**: This organism does not exhibit evisceration.

6. **Conclusion**: Since Kukumaria is the only organism listed that exhibits evisceration, the correct answer to the question is Kukumaria.

### Final Answer:
Evisceration is characteristic of **Kukumaria**.
