D All of the above
AI Explanation

The correct answer is D) All of the above. Coal, leather, and scrap rubber are all materials that can be subject to spontaneous combustion. Spontaneous combustion occurs when a material's temperature rises to the point of ignition without an external heat source. This can happen with substances that undergo slow oxidation reactions, which generate internal heat. Coal, leather, and scrap rubber all have properties that make them prone to this phenomenon, which is an important safety consideration for storage and handling on vessels.
