As a Christian, I believe that Christianity is a religion that represents love. If you decide to become a Christian, you know that God is always with you, and will never leave your side. Unlike other religions, you are free don't have strict rules because Jesus died for you. God loves you so much he sent his son to die for you. Christianity means love to me.
Since the U.S. was fighting against communist nations in WW ll, I'd say answer A.
That was when the U.S. first realized how dangerous communism is, since the whole nation in a sense follows the wants of one man.
Fighting against Hitler, Mussolini, and the other guy (I can't remember who it was) really opened America's eyes to the horrors of communism, which is why they decided to strengthen the Democratic side of America.
I believe answer A. is correct.
