A. Humerus
B. Femur
C. Tibia - fibula
D. All of the above

Answer

### Step-by-Step Solution:

1. **Understanding Nutrient Foramen**: The nutrient foramen is a small opening in the bone that allows blood vessels and nerves to enter and nourish the bone tissue.

2. **Identifying the Bones**: The question asks about the presence of nutrient foramen in specific bones: humerus, femur, tibia, and fibula.

3. **Analyzing Each Bone**:
- **Humerus**: The nutrient foramen is present in the humerus, directed away from the growing end.
- **Femur**: The femur also has a nutrient foramen, which is directed away from its growing end.
- **Tibia**: The tibia has a nutrient foramen located at its upper end, away from the growing end.
- **Fibula**: The fibula, like the other bones mentioned, also contains a nutrient foramen.

4. **Conclusion**: Since the nutrient foramen is present in all the bones listed (humerus, femur, tibia, and fibula), the correct answer is "all of the above."

### Final Answer:
The nutrient foramen is present in all of the above: humerus, femur, tibia, and fibula.
