Which bone is known as the breast bone?

• A. Scaphoid bone
• B. Sternum
• C. Scapula
• D. Silicosis

Answer: (B)

The breastbone is the sternum, a flat bone located at the center of the chest that forms the front part of the rib cage. It articulates with the ribs via costal cartilages and provides an attachment point for chest muscles, helping protect the heart and lungs. The name comes from its central, anterior position in the chest. The other options refer to different structures: the scaphoid is a wrist bone, the scapula is the shoulder blade, and silicosis is a lung disease caused by inhaling silica dust.
