Correct Answer: Option B — More oil will enter the operating cylinder (O).

Electrical load increases cause the turbine to momentarily slow, drawing governor weights inward. This action repositions the pilot valve to direct more high-pressure oil into the operating cylinder (O), opening additional nozzle valves to increase steam flow.
