Which country experienced a violent crackdown due to protests against President Daniel Ortega?

The choice of Nicaragua is correct because it was the country where significant protests erupted against President Daniel Ortega's government, particularly in 2018. These protests were sparked by discontent over various issues, including social security reforms and broader concerns about authoritarianism, corruption, and governance. The government's response was notably violent, involving police repression and forceful tactics against demonstrators, leading to numerous deaths and injuries. This brutal crackdown received widespread condemnation from international human rights organizations and highlighted the ongoing political crisis in Nicaragua.

In contrast, the other options—Costa Rica, Panama, and Honduras—have faced their own political challenges, but they have not experienced the same level of violent government repression in response to protests against their leaders in the context of this question. Costa Rica is known for its stable democracy and has not seen similar protests against Ortega's leadership. Panama has faced political protests but has not had the violent crackdown associated with Ortega's presidency. Honduras has had its own issues with political unrest, but these do not directly relate to President Ortega and the specific events in Nicaragua.
