Concept: Disaster Management cycle includes activities before, during, and after a disaster. The main stages are mitigation, preparedness, response, recovery, and reconstruction.
Step 1: Start with mitigation.
Mitigation means reducing disaster risk before the disaster occurs. Examples include safe construction, embankments, land-use planning, and risk reduction measures.
\[
A = \text{Mitigation}
\]
Step 2: Then comes preparedness.
Preparedness includes planning, mock drills, early warning systems, training, and emergency supplies.
\[
B = \text{Preparedness}
\]
Step 3: During the disaster, response is needed.
Response includes rescue, evacuation, relief distribution, medical help, and emergency communication.
\[
D = \text{Response}
\]
Step 4: After response, recovery begins.
Recovery means restoring normal life, services, livelihoods, and basic facilities.
\[
C = \text{Recovery}
\]
Step 5: Finally reconstruction is carried out.
Reconstruction includes rebuilding damaged houses, roads, bridges, schools, hospitals, and infrastructure.
\[
E = \text{Reconstruction}
\]
Therefore, the correct sequence is:
\[
A, B, D, C, E
\]
