ASprinkler heads installed in the galley and living spaces would have the same fusible link melting point.

BSprinkler heads installed in the living spaces would have a higher melting point fusible link than those installed in the galley.

CSprinkler heads installed in the galley would have a higher melting point fusible link than those installed in the living spaces.

DNone of the above; sprinkler heads with fusible links are prohibited aboard U.S. flag vessels.

AI Explanation

The correct answer is C) Sprinkler heads installed in the galley would have a higher melting point fusible link than those installed in the living spaces. According to 46 CFR Part 76, which governs fire protection equipment on vessels, sprinkler heads installed in galleys are required to have a higher temperature fusible link than those installed in living spaces. This is because the galley environment is typically hotter than living spaces, so the fusible link needs to withstand higher temperatures before activating the sprinkler. The other answer choices are incorrect because they do not accurately reflect the regulatory requirements for sprinkler head fusible link temperatures in different vessel spaces.
