Given: Scheduling inspections should be done to obtain a high level of efficiency.

Efficient scheduling minimizes travel time and maximizes inspection coverage, a practical aspect of fire inspection management (not explicitly detailed in the IFC but implied in Section 106.2, Inspections). Selecting occupancies in the same geographic area (C) reduces travel, allowing more time for thorough inspections. Option A undermines the comprehensive nature of inspections required by IFC Section 106.1. Option B could compromise inspection quality, not efficiency. Option D focuses on violation history, which doesn’t inherently improve scheduling efficiency and may skew priorities. Thus, C is the most logical and IFC-aligned choice.
