Concept / Approach:
Comprehensive flood response addresses immediate survival, sustenance, and health risks (injury, diarrhoeal disease, leptospirosis, vector-borne illness).

Step-by-Step Solution:
1) Evacuate and shelter affected populations.2) Distribute essential goods and safe drinking water.3) Deploy medical teams and preventive measures (chlorination, vaccination as indicated).

Verification / Alternative check:
Standard disaster-management protocols include all three.

Why Other Options Are Wrong:
Single/partial actions omit necessary pillars of response.

Common Pitfalls:
Ignoring public-health risks that follow flooding.

Final Answer:
All follow.
