Answer & Explanation
The correct answer is Option A: Prevent additional oxygen from reaching the fire.
Forcing ventilation into a compartment with a fire provides an additional supply of oxygen, which fuels the combustion process. Securing the ventilation (Option A) removes this oxygen source, aiding in fire suppression, consistent with removing an element of the fire triangle.
