Which Cuban leader led the revolution and became the country's communist dictator?

• A. José de San Martín
• B. Che Guevara
• C. Fidel Castro
• D. Raul Castro

Answer: (C)

The important idea here is recognizing who led the Cuban Revolution and then ruled Cuba as a communist dictator. Fidel Castro fits that description: he headed the rebel movement that overthrew Batista in 1959 and then established Cuba as a socialist state aligned with the Soviet Union, governing for decades. Che Guevara was a key revolutionary figure and ally, but he never became the country’s ruler. Raul Castro later took leadership after Fidel, but he did not lead the revolution or become the initial dictator. José de San Martín was a figure from South American independence movements, not Cuba’s revolution.
