C. Cranial and ear ossicles
D. Facial and ear ossicles

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the two sets of bones that make up the human skull.

2. **Identifying the Sets of Bones**: The human skull is divided into two main parts:
- **Cranial Bones**: These are the bones that form the protective case around the brain. There are a total of 8 cranial bones.
- **Facial Bones**: These bones form the front part of the skull and consist of 14 skeletal elements.

3. **Counting the Total Number of Bones**: When combined, the cranial and facial bones total 22 bones in the human skull (8 cranial + 14 facial = 22).

4. **Eliminating Incorrect Options**:
- **Facial and Hyoid**: The hyoid bone is not part of the skull; it is located in the neck.
- **Cranial and Ear Ossicles**: Ear ossicles are small bones in the middle ear, not part of the skull structure.
- **Facial and Ear Ossicles**: Again, ear ossicles are not part of the skull.

5. **Conclusion**: The correct answer is that the human skull is composed of **Cranial and Facial bones**.

### Final Answer:
The skull of a human is composed of two sets of bones: **Cranial and Facial bones**.
