Final answer:
Cuban Americans are the second-largest Hispanic subgroup in the United States, with significant immigration following Castro's rise to power in 1959 and peaking with the Mariel boatlift in 1980.
Step-by-step explanation:
The correct answer to the question is C) Cubans. Cuban Americans are the second-largest Hispanic subgroup in the United States. Their significant wave of immigration began after Fidel Castro's rise to power in 1959, a period marked by the communist revolution in Cuba. A notable moment in Cuban immigration was the Mariel boatlift in 1980. Unlike other Hispanic groups, many Cuban immigrants had higher socioeconomic status upon arrival in the U.S., and they were often seen as refugees fleeing communism, which garnered them unique support and services from the U.S. government. In particular, the Cuban community has had a strong presence in Miami, Florida, where they have become influential in politics and professional life.
