Answer: C

Explanation:

A special sprinkler is a device for use in applications requiring special water discharge patterns, directional spray, or other unusual discharge characteristics, as defined by NFPA 13. Examples of special sprinklers include residential sprinklers, exposure protection sprinklers, water curtains, and sprinkler-protected glazing. Special sprinklers have different design and installation requirements than standard spray sprinklers.

Reference: NFPA 13, 2019 edition, section 3.3.27.1; NFPA 13 Handbook, 2019 edition, page 31.

A special sprinkler is designed for specific applications that require unique water discharge patterns, directional spray, or other specialized discharge characteristics. These sprinklers are tailored for particular fire risks or architectural constraints where standard sprinklers may not provide adequate protection.

Reference: NFPA 13’s definitions and classifications of sprinklers, including special sprinklers for unique fire protection challenges.
