Answer & Explanation
The correct answer is Option B: B) Fog pattern.
For initial cooling in a confined space, a fog pattern nozzle is recommended. The fine water droplets rapidly absorb heat and turn into steam, displacing oxygen and pushing back heat and smoke, thereby improving conditions for firefighters and preventing flashover.
