Explanation:
To understand this answer we need to analyze all of the options.
A) is incorrect because the soviets never incurred in any operation to destroy the missiles. Instead, they played a slow move of escalated tensions that developed a conflict called "The cold war" because there was no action, only strategic moves.
b) is correct. After the united states installed nuclear missiles in strategic points forming a belt to prevent any breach from the soviets expansionist moves, the soviets looked for allies to counter that belt of contention, and Cuba was the chosen one.
c) They didn't try to negotiate a nuclear disarm deal. It was the U.S. the one looking for it. The Soviets wanted to remain in a strong position.
d) They didn't threaten to start another war with the United States because they never had more than a cross firefight at the end of the great war. So, this is incorrect.
