AI Explanation
The correct answer is D) stop-check valves installed in the bilge suction manifolds. Explanation: Accidental flooding of the engine room bilges through the bilge system is prevented by the installation of stop-check valves in the bilge suction manifolds. These valves allow water to be pumped out of the bilges but prevent water from accidentally flowing back into the bilges, which could lead to flooding. The other options, while related to bilge systems, do not specifically address the issue of preventing accidental flooding through the bilge system.
