Statement — Large parts of the low-lying areas in the city are inundated due to heavy downpour over the last few days.\nCourses of Action:\nI. The local administration should immediately make the necessary arrangements to move the affected people to safe places.\nII. The local administration should deploy fire brigade personnel in these areas to save the affected people.

Introduction / Context:
Widespread flooding requires swift disaster-management steps prioritized around life safety. The actions should reflect the core competencies of agencies and the immediacy of evacuation needs.

Given Data / Assumptions:

• Sustained heavy rain has inundated low-lying areas.
• I: Arrange to move affected people to safe places (evacuation, shelters).
• II: Deploy fire brigade personnel in these areas to save people.

Concept / Approach:
In flood scenarios, the first response is evacuation, sheltering, and medical support. While fire brigades sometimes assist in rescues, they are specialized for fires; flood-and-rescue teams, disaster-response forces, civil defense, and boats are typically more appropriate. The course of action should be precise and immediately applicable.

Step-by-Step Solution:
I directly addresses life safety: evacuation logistics, temporary shelters, food, water, and medical care. It is an immediate, universally accepted response.II names a specific agency (fire brigade) whose primary mandate is fire-fighting. In absence of details about capacity, equipment (boats), and training for water rescue, the instruction risks misallocation. Better phrasing would be 'deploy appropriate disaster-response/rescue teams.' Hence, II as stated is not the best immediate directive.

Verification / Alternative check:
Many municipalities deploy NDRF/SDRF, civil defense, and police with flood equipment, while fire brigades support as needed. But the generalized directive should prioritize evacuation (I), not necessarily fire brigades (II).

Why Other Options Are Wrong:
Only II: Mandates a possibly suboptimal agency. Both: Overcommits. Neither: Ignores the obvious need to evacuate.

Common Pitfalls:
Assuming any emergency unit is optimal for all hazards. Matching capability to hazard is key.

Final Answer:
Only I follows.
