Answer:
B. Sucking chest wound
Explanation:
A sucking chest wound occurs when a hole, of the size of a coin, is created in the chest cavity that protects the lungs, resulting in the collapse of the lung. Such hole can be created from injuries that involve the puncturing of the chest cavity by foreign objects such as from gunshot, stabs etc. When the lung becomes collapse as a result of a puncture in the chest cavity, the individual would try hard to suck for air while breathing. As the individual breathes in and out, hissing or sucking sound can be heard. Coughing out of blood may be observed too.
