The correct answer is 3. The United States attempted to prevent the spread of communism to Grenada by using U.S. troops to invade Grenada after its prime minister was removed by radicals.

Explanation:

The invasion of Grenada, codenamed Operation Urgent Fury, occurred on October 25, 1983 when Grenada was invaded by the United States, Antigua and Barbuda, Barbados, Dominica, Jamaica, Saint Lucia and Saint Vincent and the Grenadines. The background was that the island's leftist leader Maurice Bishop had seized power in 1979 in a revolution that ousted then-authoritarian Prime Minister Eric Gairy, and had brought Grenada closer to states such as the Soviet Union and Cuba. On October 19, 1983, in turn, power was seized by the equally Soviet-friendly Bernard Coard, who was Bishop's deputy prime minister. In this situation, the East Caribbean Organization asked the United States, Barbados and Jamaica to intervene, which led to the invasion on October 25.
