The cold war was not a physical war, but more of a political war. No fighting, shooting, or bombing happened during the "war". Instead, it was a war of politics and threats. The U.S. and the U.S.S.R. were constantly at the brink of full nuclear war, if one country fired all their nukes, the other would do the same shorty, leaving both countries demolished within minutes of each other. Other things that happened during this time were the "red scare," which was a fear of communists coming into America and America's politics and the space race, seeing which country would not only send mechanics into space but men as well.
I believe it's B because popular sovereignty deals with the government receiving its power from the government and people have the right to speak up and disagree
