Answer:
Step-by-step explanation:
Demobilization generally refers to the army being reduced or disbanded altogether. It comes about because it (the army) is no longer needed to fight a way.
Demobilization can also refer to a construction site where men and equipment are no longer needed.
The answer is pretty tricky because neither of these definitions are listed. D is a consequence of demobilization. It is a result of demobilization. I would pick it, but don't be surprised if you get it wrong. Bring up your objection and then be quiet.
