The correct answer is C.
The nuclear arm race was an arms race competition for supremacy in nuclear warfare between the United States and the Soviet Union during the cold War.
Both countries tried to surpass each other, which created a competition between them. The competition consisted of competitive acquisition of military capability reflecting an adversarial relationship.
Arm races are always a negative occurrence in both economic and security terms. They require large economic resources and they might heighten fear and hostility between the involved countries. This might also lead to an outbreak of war.
