Apermitted, provided they are fitted with caps or plugs
Brequired, if there are no separators installed on board
Cnot required, provided there is a high and low tank suction
Dstrictly prohibited
AI Explanation
The correct answer is A) permitted, provided they are fitted with caps or plugs. The reasoning for this is that the regulations for diesel fuel oil systems require fittings to be either flared or fitted with caps or plugs. This is to prevent any potential leakage or spills from the fuel system. The other options are incorrect because B) requiring separators is not a regulation for this specific fitting requirement, C) not requiring caps/plugs is incorrect as they are mandatory, and D) prohibiting these fittings altogether is too strict and not in line with the actual regulations.
