With an approved combination nozzle, low-velocity fog is produced by _______________.

A the combination nozzle only when the water pressure exceeds 125 psi
B inserting an applicator in the nozzle
C directing a straight stream of water against the ship's structure
D putting the handle of the nozzle in the forward position
AI Explanation

The correct answer is B) inserting an applicator in the nozzle. With an approved combination nozzle, low-velocity fog is produced by inserting an applicator in the nozzle. This allows the nozzle to convert the straight stream of water into a wide, low-velocity fog pattern, which is useful for fire-fighting and decontamination purposes. The other answer choices are incorrect because they do not accurately describe how low-velocity fog is produced with a combination nozzle.
