In Sea Anemone, the symmetry is

Options

A. Radial
B. Spherical
C. Bilateral
D. Absent.

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about the symmetry of the sea anemone, which is a marine animal belonging to the phylum Cnidaria.

2. **Understand the Characteristics of Sea Anemone**: Sea anemones are soft-bodied and resemble flowers. This characteristic can give us clues about their structure and symmetry.

3. **Define Symmetry Types**:
- **Radial Symmetry**: An organism exhibits radial symmetry if it can be divided into similar halves by passing a plane through its central axis.
- **Bilateral Symmetry**: An organism has bilateral symmetry if it can be divided into two equal halves only along one plane.
- **Spherical Symmetry**: An organism has spherical symmetry if it can be divided into similar halves in any plane passing through its center.
- **Absent Symmetry**: This means the organism does not exhibit any form of symmetry.

4. **Analyze Sea Anemone's Symmetry**: Given that sea anemones are sessile (fixed in one place) and their body structure allows for division into equal halves from multiple angles around a central point, they exhibit radial symmetry.

5. **Eliminate Incorrect Options**:
- Spherical symmetry is not applicable as sea anemones do not have a spherical shape.
- Bilateral symmetry is also incorrect since sea anemones do not have a distinct left and right side.
- Absent symmetry is incorrect because sea anemones clearly exhibit a form of symmetry.

6. **Conclusion**: The correct answer is that sea anemones exhibit **radial symmetry**.

**Final Answer**: The symmetry in sea anemone is **radial symmetry**.
