This ensures that there is sufficient hydraulic pressure available for subsequent starting attempts if needed. The other answer choices are incorrect - B) is for engaging the starter motor, C) is for filling the hydraulic system sump, and D) is for bypassing the hydraulic motor when the engine is running, which is not the purpose of the engine-driven pump in the starting system.
