The struts of the GE LM2500 compressor front frame provide passages for all of the following mediums EXCEPT which of the following?

Correct Answer: Option B — Fuel oil

The compressor front frame struts serve as structural supports and conduits for various fluids. They provide passages for lube oil supply, scavenge oil return, and seal-pressurization air. Fuel oil is delivered to the combustor section through external fuel manifolds and nozzles, not through the internal passages of the front frame.
