The correct option is C President Kennedy ordered the U.S. Navy to turn back Soviet ships headed for Cuba
In April 1961, the leaders of the Union of Soviet Socialist Republics (USSR) were worried that the United States of America (USA) would invade communist-ruled Cuba and overthrow Fidel Castro, the president of the small island nation off the coast of the United States. 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. 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.
