Correct Answer: Option C — cylinder should extend

Energizing solenoid 'A' shifts the directional control valve spool to align the pump discharge with the cap end of the cylinder. This increases pressure on the piston face, causing the cylinder to extend. This is a standard configuration for electrically operated hydraulic actuators found in various marine auxiliary systems.
