Why C is correct
Fires in ordinary combustible materials are Class A fires. Both 46 CFR §28.265(d)(9)(iii) and 46 CFR §185.512(a)(3)(iii) specify that water is appropriate for fires in ordinary combustible materials, and portable extinguishers may also be used. Fixed suppression systems are specified for machinery spaces, not open deck Class A fires.
