- A. Annealed seamless copper with a minimum wall thickness of 0.9 mm
- B. Brass or nickel-copper alloy tubing

- D. Nonmetallic flexible hose reinforced with wire braid
Why C is correct
46 CFR §28.835(k) specifically requires supply piping conveying fuel oil or lubricating oil in close proximity to equipment or lines with an open flame or parts operating above 260 °C (500 °F) to be of seamless steel. The other metallic and nonmetallic options permitted elsewhere in §28.835 do not satisfy this elevated-temperature proximity requirement.
