Which of the following factors contributed to Hurricane Katrina’s becoming one of the deadliest natural disasters in US history?

Climate change decreased the number of tropical cyclones that form in the Atlantic basin, causing coastal residents to be inadequately prepared.
Heavy rainfall from the hurricane overwhelmed aging levees and flooded areas that were below sea level and populated mainly by families with low incomes.
The hurricane caused a tsunami that flooded low-lying areas all along the Gulf Coast and destroyed most of New Orleans.
Government officials inaccurately predicted the hurricane’s path, leading many residents to remain in the most vulnerable areas.
