b) It proved that a naval blockade was not an act of war.
c) It showed Cuba that communism should be stopped.
d) It brought the world dangerously close to nuclear war.
The correct statement is D. Historians agree the Missile Crisis was the closest the world got to have a nuclear war between the U.S. and USSR. Nothing before or after this came as close to be direct aggression from one of these countries against the other.
