Answer
Correct Answer: All follow
Explanation
Introduction / Context:With imminent flood risk due to silted river beds, immediate life-safety and communication measures are essential, followed by medium-term mitigation (desilting).
Given Data / Assumptions:
- I: Evacuate vulnerable populations.
- II: Issue mass alerts via radio/TV.
- III: Desilt post-flood to restore capacity.
Concept / Approach:Evacuation and alerts reduce casualties; desilting increases carrying capacity and reduces future risk.
Step-by-Step Solution:1) Trigger staged evacuation.2) Broadcast warnings and safety guidance.3) Plan desilting after water recedes, with environmental safeguards.
Verification / Alternative check:Disaster protocols support all three actions.
Why Other Options Are Wrong:Partial choices ignore either immediate safety or future prevention.
Final Answer:All follow.
