Triploblastic animals show

Options

A. asymetry
B. radial symmetry
C. bilateral symmetry
D. spherical symmetry

Answer

**Step-by-Step Solution:**

1. **Understanding Triploblastic Animals**: Triploblastic animals are characterized by having three germ layers during their embryonic development: ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer).

2. **Identifying Types of Symmetry**: The question presents four types of symmetry:
- Asymmetry: No symmetry at all.
- Radial symmetry: Body parts arranged around a central axis.
- Bilateral symmetry: Body can be divided into two mirror-image halves.
- Spherical symmetry: Body parts arranged in a spherical manner.

3. **Linking Germ Layers to Symmetry**: Triploblastic animals, due to their complex body structure, typically exhibit bilateral symmetry. This means that if you draw a line down the middle of the body, both sides will be mirror images of each other.

4. **Conclusion**: Based on the characteristics of triploblastic animals and the types of symmetry, the correct answer to the question is that triploblastic animals show bilateral symmetry.

5. **Final Answer**: The correct option is **bilateral symmetry**.
