The correct answer is C) greater range than low-velocity fog. The high-velocity fog position on an all-purpose nozzle is designed to produce a finer, more atomized water spray compared to the low-velocity fog setting. This finer spray pattern has greater range and can project the water further than the low-velocity fog setting, which produces larger water droplets. The high-velocity fog can achieve a greater reach and penetration than the low-velocity fog, making it more effective for certain firefighting applications. The other options are incorrect because A) the high-velocity fog would have a greater range than the low-velocity fog, and B) and D) are contradictory to the principle that the high-velocity fog setting produces a finer, longer-reaching spray pattern.
