Options

A. Pectoral girdle
B. Fore limbs
C. Hind limbs
D. Pelvic girdle.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Clavicle**: The clavicle, commonly known as the collarbone, is a long bone that serves as a critical component in the skeletal system.

2. **Identifying the Role of the Clavicle**: The primary function of the clavicle is to act as a support structure for the shoulder. It connects the arm to the body and helps stabilize the shoulder joint.

3. **Locating the Clavicle in the Body**: The clavicle is located in the upper part of the body, specifically at the junction of the arm and the trunk.

4. **Connecting to the Pectoral Girdle**: The clavicle is a key part of the pectoral girdle (also known as the shoulder girdle), which consists of the clavicle and the scapula (shoulder blade). This girdle supports the upper limbs and allows for a wide range of motion.

5. **Eliminating Other Options**:
- **Forelimbs**: The forelimbs refer to the arms, which the clavicle supports but does not constitute.
- **Hind Limbs**: The hind limbs refer to the legs, which do not include the clavicle.
- **Pelvic Girdle**: The pelvic girdle is part of the lower trunk and does not include the clavicle.

6. **Conclusion**: Based on the above points, the clavicle is correctly identified as a constituent of the pectoral girdle.

**Final Answer**: The clavicle is a constituent of the pectoral girdle.
