Correct Answer: Option C — To allow venting of combustion products from the fire to the atmosphere.

Opening doors and portholes facilitates the venting of smoke and hot combustion gases. This process, known as ventilation, improves visibility and reduces the temperature for firefighting teams. It is a controlled tactical maneuver used to manage the fire environment and prevent the buildup of explosive gases.
