The struts of the compressor front frame provide passages for all of the following mediums EXCEPT for which of the following?

Correct Answer: Option A — Fuel oil

Compressor front frame struts are designed to route lube oil, scavenge oil, and seal-pressurization air through the engine's structural core. Fuel oil is never routed through these structural struts to prevent potential fire hazards or contamination within the engine's internal air passages, adhering to strict marine safety standards.
