Which of the following best explains why the U$.$S$.$ decided to prioritize the war in Europe in terms of commitment of troops, funding, weapons, and supplies?

The Germans were very advanced technologically, and the Americans feared they could use weapons like rockets and atomic weapons to win the war.

All of these are correct

America's European allies were under attack from the Germans, and there was a possibility they could be defeated by the Germans unless the U$.$S$.$ intervened quickly.

The European theater allowed the greatest opportunity for the U$.$S$.$ and its allies to launched a combined offensive, pulling their resources to go after Germany and Italy.
