Clavicle is also known as breastbone.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that the clavicle is also known as the breastbone. We need to analyze if this is true or false.

2. **Identifying the Clavicle**: The clavicle, commonly known as the collarbone, is a bone that connects the arm to the body. It is located between the sternum (breastbone) and the shoulder.

3. **Identifying the Breastbone**: The breastbone is scientifically referred to as the sternum. It is a flat bone located in the center of the chest and serves as a point of attachment for the ribs.

4. **Clarifying the Relationship**: The clavicle is not the same as the sternum. While the clavicle connects the arm to the body, the sternum is the breastbone that is part of the ribcage.

5. **Conclusion**: Since the clavicle and the sternum (breastbone) are two different bones with distinct functions, the statement "Clavicle is also known as breastbone" is false.

**Final Answer**: The statement is false. The clavicle is not known as the breastbone; the breastbone is called the sternum.
