What is the name associated with the dividing bulkheads separating the accommodation spaces from the engine room of a ship?

Correct Answer: Option A — Engine casing

The engine casing is the structural enclosure surrounding the engine room opening, extending upward through the decks. It serves as a fire-resistant boundary separating the machinery space from accommodation areas, while also providing a path for ventilation, exhaust uptakes, and emergency access to the engine room.
