Answer: C

Explanation:

ESFR (Early Suppression, Fast Response) sprinklers are designed for high-challenge fire hazards like rolled paper storage. The hose stream allowance for such systems is typically higher to account for the potential need for manual firefighting assistance. 500 gpm for 120 minutes provides a substantial water supply for this purpose.

Reference: Based on NFPA 13’s guidelines for storage and ESFR sprinkler systems.
