Answer:
A (or the first one) is the answer
The main reason why the the United States did not sign the Treaty of Versailles is because they thought it was a bad idea to "punish" Germany by demanding massive reparations payments, and the US turned out to be right, since this only caused Germany to rise up militarily once again.
The significance of military action in WWII is that without taking this necessary action, (assuming you are referring to the U.S.) WWII could have had a very different outcome. The U.S. involvement in WWII was the cause of the bombing of Pearl Harbor. If they hadn't formed the Allied Forces to defeat Germany and Hitler, Germany very well might have won.
