The correct answer is: a) Minimize the impact of disasters.
Disaster risk reduction (DRR) is a systematic approach to lessening the adverse impacts of hazards and the associated disaster risks on people, property, and the environment. DRR aims to reduce the underlying risk factors that make people, places, and systems vulnerable to hazards, as well as the capacity of society to cope with the impacts of hazards.
Option b) is incorrect because predicting hazard occurrences is not the same as reducing the impact of disasters. Predicting hazard occurrences can help to mitigate the impact of disasters by giving people time to prepare, but it does not necessarily reduce the underlying risk factors that make people, places, and systems vulnerable to hazards.
Option c) is incorrect because providing post-disaster relief is not the same as reducing the impact of disasters. Providing post-disaster relief can help to mitigate the impact of disasters by providing assistance to those who have been affected, but it does not necessarily reduce the underlying risk factors that make people, places, and systems vulnerable to hazards.
Option d) is incorrect because controlling natural phenomena is not possible. Natural phenomena are beyond human control, and attempts to control them can often have unintended consequences. Instead, DRR focuses on reducing the vulnerability of people, places, and systems to natural hazards.
