Answer & Explanation
The correct answer is Option A: A) Convection.
Closing fire doors prevents the spread of fire and smoke primarily through convection, which is the transfer of heat by the movement of hot gases and air. This compartmentalization is a key passive fire protection strategy as per SOLAS requirements.
