AI Explanation
The correct answer is A) flared. According to 46 CFR Part 56, which covers marine piping systems, steel tubing connections and fittings used with diesel fuel oil systems are required to be either flared or brazed. Flaring the ends of the steel tubing creates a leak-proof connection that can withstand the pressures and temperatures associated with diesel fuel oil systems. The other answer choices (B, C, and D) are not specified in the regulations as acceptable methods for these types of connections.
