Answer: B

Explanation:

NFPA 13 requires a minimum vertical clearance between HVLS fans and sprinklers to prevent interference with the sprinkler spray pattern. A 24 in. (600 mm) clearance is commonly recommended to ensure that the fan does not disrupt the distribution of water in the event of a fire.
