Why B is correct
The IBC expressly directs Group I-2 occupancies and ambulatory care facilities to mechanical ventilation under IMC Section 407. It does not establish one universal outdoor-air percentage for all rooms; the applicable mechanical-code healthcare provisions must determine the detailed requirements.
