Answer & Explanation
The correct answer is Option D: D) Flashover of confined vapor clouds.
Fuel oil fires in confined engine room spaces can lead to rapid heat accumulation and the build-up of flammable vapors. If these vapors reach their lower explosive limit, a 'flashover' or explosion can occur, posing a severe threat to the vessel.
