Correct Answer: Option B — Excess oil under high-pressure is released from the spring loaded accumulators to the sump.

Hydraulic governors utilize internal positive displacement pumps and spring-loaded accumulators to maintain high-pressure operating oil. Excess oil delivered by the pump is continuously relieved by these accumulators back to the internal sump to regulate operating pressure.
