placed fulgencio batista in power.
formed an alliance with the united states.
formed an alliance with the soviet union.

Explanation:

After the Cuban Revolution of 1959, Fidel Castro led Cuba. The U.S. had supported Batista (so option 1 is wrong). The U.S. imposed an embargo on Cuba (so option 2 is wrong). Cuba, under Castro, moved towards a socialist - like system (not capitalist, so option 4 is wrong). Due to U.S. hostility, Cuba formed an alliance with the Soviet Union.

Answer:

formed an alliance with the Soviet Union.
