Answer

To determine the number of unpaired bones in the cranium, we can follow these steps:

1. **Understand the Structure of the Cranium**: The human cranium is made up of a total of 28 bones. These bones can be categorized into paired and unpaired bones.

2. **Identify the Paired and Unpaired Bones**: Out of the 28 bones, there are 8 paired bones and 6 unpaired bones. The paired bones are those that come in pairs (one on each side), while unpaired bones are singular.

3. **List the Unpaired Bones**: The unpaired bones in the cranium include:
- Frontal bone
- Occipital bone
- Sphenoid bone
- Ethmoid bone
- Vomer
- Mandible

4. **Count the Unpaired Bones**: By counting the listed unpaired bones, we find that there are a total of 6 unpaired bones in the cranium.

5. **Select the Correct Option**: Given the options (2, 4, 6, and 1), the correct answer is 6.

**Final Answer**: The number of unpaired bones in the cranium is 6.
