Solution

The correct option is C The man dies as the lungs get collapsed.
In humans, the lungs are situated in the thoracic chamber which is anatomically an air-tight chamber. If the lungs are punctured it will collapse due to the decreased air pressure which will further lead to death.
So, the correct answer is option B.
