Options

A. Sternum

C. Coracoid
D. Clavicle

Answer

To solve the question "The collar bone is common name for", we will analyze each of the options provided:

1. **Sternum**:
- The sternum, also known as the breastbone, is a flat bone located in the center of the chest. It connects to the ribs via cartilage and is not commonly referred to as the collarbone.

2. **Scapula**:
- The scapula, or shoulder blade, is a flat triangular bone located in the upper back. It connects the humerus (arm bone) with the clavicle (collarbone) but is not itself the collarbone.

3. **Coracoid**:
- The coracoid is not a bone that exists independently in the human body; rather, it refers to a small hook-like structure called the coracoid process, which is part of the scapula. Therefore, it cannot be the collarbone.

4. **Clavicle**:
- The clavicle, commonly known as the collarbone, is a long, horizontal bone that connects the arm to the body. It is located above the first rib and is part of the shoulder girdle.

Based on the analysis of the options, the correct answer is:
**D. Clavicle**
