Answer:
c)The Bay of Pigs ended the stand off.
Explanation:
The tensions between Cuba and The United States of America really reached a noticeable point in the 1950s. That was after Fidel Castro ousted US-backed dictator Fulgencio Batista. This action eventually caused the Botched Invasion in 1961 at the Bay of Pigs. This all happened a few years before what came to be known as the "Cuban missile crisis".
