During explosive decompression, the rapid loss of cabin pressure can lead to a number of dangerous conditions, including exposure to wind blast and extreme cold. This happens because, as the cabin pressure drops suddenly, the outside air, which is at a much lower temperature, rushes into the cabin. The wind blast can create a violent and turbulent environment inside the aircraft, which poses risks to the crew and passengers. Additionally, the extreme cold can cause physiological effects, such as hypothermia, and can affect the operation of the aircraft's systems if measures to maintain cabin temperature are compromised.

The other options do not relate to the immediate physical dangers presented by explosive decompression. For example, while reduced fuel efficiency and excessive cabin heating are relevant in different contexts, they are not direct consequences of explosive decompression. Similarly, loss of communication with ground control is a concern during various flight situations but is not a direct danger associated with the explosive decompression itself. Thus, the exposure to wind blast and extreme cold is a primary concern that clearly represents the dangers of explosive decompression during flight.
