Leave it to the fire marshal to come up with a question that sounds like a word problem from math class. Options A and B seem too low, so I'll go with C.

I'm going with Option D. The storage height and lack of in-rack sprinklers make me think a higher density is required.

Interesting point, but I still think 0.33 gpm/ft2 (13 mm/min) makes more sense based on the overall setup of the warehouse.

I disagree, I believe it is 0.44 gpm/ft2 (17.9 mm/min) because of the aisle width and the sprinkler heads being used.

I think the required density is 0.33 gpm/ft2 (13 mm/min) because of the height of the storage and the type of commodity.

Option C looks right to me. 0.44 gpm/ft2 seems to be the appropriate density for this scenario.
