Abrass
Bcopper
Ciron
Dmonel metal or stainless steel
AI Explanation
The correct answer is D) monel metal or stainless steel. Fuel oil strainer disks, spacers, and scraper blades are typically made of monel metal or stainless steel to minimize corrosion. These materials are highly resistant to corrosion, especially in the presence of fuel oil, which can be corrosive. Brass and copper are more susceptible to corrosion in this environment, while iron is also prone to rusting and corrosion. Therefore, monel metal or stainless steel are the preferred materials to ensure the longevity and proper functioning of these fuel system components on vessels.
