D. Fibula.

Answer

**Step-by-Step Solution:**

1. **Understanding the Forelimb**: The forelimb refers to the upper limb of the body, which includes the arm and hand.

2. **Identifying the Bones in the Forelimb**: The main bones in the forelimb include:
- Humerus (the upper arm bone)
- Radius (one of the two bones in the forearm)
- Ulna (the other bone in the forearm)
- Carpals (the wrist bones)
- Metacarpals (the bones of the hand)
- Phalanges (the finger bones)

3. **Focusing on the Humerus**: The humerus is a long bone that connects the shoulder to the elbow and is the primary bone of the upper arm.

4. **Articulation with the Pectoral Girdle**: The humerus articulates with the pectoral girdle, which consists of the scapula (shoulder blade) and clavicle (collarbone). This connection allows for a wide range of motion in the arm.

5. **Distinguishing Between Limbs**: It is important to differentiate between the forelimb and the hind limb. The hind limb includes bones such as the femur, tibia, and fibula, which are not part of the forelimb.

6. **Conclusion**: Based on the information, the correct answer to the question "Which one is a bone of the forelimb?" is the **humerus**.

**Final Answer**: The bone of the forelimb is the **humerus**.
