Comprehensive and Detailed Step-by-Step Explanation:
Occupant Load Calculation:
According to NFPA 101 (Life Safety Code), Table 7.3.1.2, for assembly occupancies without fixed seating (such as conference rooms), the occupant load factor is:
15 ft² (1.4 m²) per person.
Calculation:
Divide the total area of 900 ft² by 15 ft per person: 900ft2/15ft2/person=60people900 \, \text{ft}^2 \, / \, 15 \, \text{ft}^2/\text{person} = 60 \, \text{people}900ft2/15ft2/person=60people Other Options Explained:
Option A (30 people): Too low.
Option C (90 people) and Option D (120 people): Exceed the calculated occupant load.
Summary:
The maximum occupant load for a 900 ft² conference room is 60 people.
