The correct answer is B) The hydrogen bomb was more destructive than the atomic bomb.
During the Cold War arms race, the hydrogen bomb differed from the atomic bomb in that the hydrogen bomb was more destructive than the atomic bomb.
Those wear the conflictive years of the Cold War and arms race. The Soviet Union wanted to be one step ahead of the United States and vice-versa. The USSR had advanced in the fabrication of its own atomic bomb, so President Harry S. Truman ordered the continuation of the fabrication of the Hydrogen bomb in 1950, a more powerful and destructive weapon. Due to this rivalry, the world was on the brink of another world war in 1962, with the Cuban Missile crisis.
