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

Correct Answer: Option A — Fuel oil

Compressor front frame struts are designed to route lube oil, scavenge oil, and seal-pressurization air to internal engine components. Fuel oil is delivered via external lines directly to the fuel manifold and nozzles, as routing high-pressure fuel through internal frame struts would pose an unacceptable fire risk.
