Answer & Explanation
The correct answer is Option C: left closed with vents off until all boundaries are cool.
After a CO2 discharge, the space should remain closed with ventilation secured until all boundaries have cooled down. Opening the space too soon can introduce oxygen, potentially causing re-ignition or flashover due to residual heat, a critical post-fire procedure to prevent secondary incidents.
