Answer:
C. The Axis Powers would have to give up completely without any compromises.
Step-by-step explanation:
The Axis Powers were too large a threat. As long as they remained in power, the possibility stood of them forging alliances with other countries and rising to prominence again. The Allies would require an unconditional surrender and strip the Axis Powers of their strength, essentially intervening.
If you recall, the allies dropped a nuke on Japan. Shortly after, the death, destruction, carnage, and mass casualties of innocent lives prompted Japan to completely surrender. This was an example of an unconditional surrender during this time period, which the allies accepted.
