An office area is defined as a light hazard occupancy. According to NFPA 13, standard spray sprinklers are a suitable type of fire protection for this classification. Control Mode Specific Application (CMSA) sprinklers are specifically designed and listed for the protection of storage occupancies, not commercial office spaces. Residential sprinklers are listed for use in dwelling units to address the unique fire risks in a residential setting. Among the given options, only standard-response spray sprinklers represent the correct category of sprinkler for a light hazard commercial occupancy.

A. quick-response CMSA sprinklers: CMSA sprinklers are not listed or suitable for light hazard occupancies like offices; they are intended for storage protection.

B. standard-response CMSA sprinklers: CMSA sprinklers are not listed or suitable for light hazard occupancies like offices; they are intended for storage protection.

D. residential sprinklers: Residential sprinklers are specifically listed for use within dwelling units and are not appropriate for a commercial office space.

1. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 Edition). Section A.4.3.2, Table A.4.3.2, "Examples of Occupancies for Hazard Classifications," explicitly lists "Offices" under Light Hazard Occupancies.

2. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 Edition). Section 7.2.3.1 states that CMSA sprinklers "shall be installed in accordance with the requirements of Chapters 20 through 25," which cover storage occupancies. This precludes their use in a light hazard office.

3. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 Edition). Section 7.2.4.1 limits the use of residential sprinklers to dwelling units, making them unsuitable for a commercial office.

4. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 Edition). Section 9.4.2.1 generally permits the use of standard-response sprinklers in all occupancy classifications unless other requirements apply. While Section 9.4.2.2 requires quick-response sprinklers for new light hazard occupancies, the standard-response spray sprinkler is the only fundamentally correct sprinkler type for this application among the choices.
