Frog skull is

Options

A. Noncodylic
B. Dicondylic
C. Monocondylic
D. None of these

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Frog Skull**:
- The frog skull is part of its skeletal system and is crucial for its attachment to the body. It is important to identify how the skull connects to the vertebral column.

2. **Identifying the Type of Skull**:
- The frog skull can be classified based on the number of condyles present. Condyles are rounded ends of bones that articulate with another bone.

3. **Observing the Foramen Magnum**:
- The foramen magnum is a large opening at the base of the skull through which the spinal cord passes. In frogs, this structure is clearly visible.

4. **Locating the Occipital Condyles**:
- Beneath the foramen magnum, there are two occipital condyles. These condyles are crucial for the articulation of the skull with the vertebral column.

5. **Determining the Classification**:
- Since there are two occipital condyles present, the frog skull can be classified as a bicondylar skull. The presence of two condyles means it cannot be classified as non-condylic or monocondylic.

6. **Conclusion**:
- Therefore, the correct classification for the frog skull is **di-condylic** (or bicondylar), as it has two condyles.

### Final Answer:
The frog skull is **di-condylic**.
