The correct answer is B) attach an applicator to the nozzle in place of the bronze nozzle tip. To get low-velocity fog from an all-purpose nozzle, you would need to replace the bronze nozzle tip with a special fog applicator. The bronze nozzle tip is designed to produce a solid stream of water, while the fog applicator is specifically engineered to create a low-velocity fog pattern. Attaching the fog applicator to the nozzle in place of the bronze tip is the correct way to achieve the desired low-velocity fog output. The other answer choices are incorrect because: A) attaching an applicator to the solid stream outlet would not produce fog, C) attaching the bronze tip to the fog outlet would not create the necessary low-velocity fog, and D) simply moving the handle to the vertical position would not change the nozzle's output.
