**Core Concept**
Fractures in boxing are often caused by the transmission of force from the fist to the bone, resulting in a break. The most common type of fracture in this context is one that occurs due to the compression and shear forces generated by the impact.
**Why the Correct Answer is Right**
The correct answer is a **Boxer's Fracture**. This type of fracture occurs at the neck of the fifth metacarpal bone in the hand. When a boxer hits with a closed fist, the force of the impact is transmitted up the forearm and into the hand, causing the metacarpal bone to break. This is due to the bending and twisting forces that occur in the wrist and hand during the impact.
