B and C

Three weeks after the Soviet Union had placed the nuclear weapons in Cuba, the Americans became aware of it. The US President, John F. Kennedy, and his advisers were reluctant to do anything that might lead to full-scale nuclear war between the two countries, but they were determined to get Khrushchev to remove the missiles and nuclear weapons from Cuba. Kennedy ordered American warships to intercept any Soviet ships heading to Cuba as a way of warning the USSR of his seriousness. A clash seemed imminent in what came to be known as the Cuban Missile Crisis.
