What components are found in the power steering system?

The power steering system is designed to assist the driver in steering the vehicle by reducing the amount of effort needed to turn the steering wheel. The components listed include the cylinder, piston, rotary valve, reservoir, and pump, all of which play crucial roles in the functionality of this system.

The pump creates hydraulic pressure that assists in steering. The reservoir holds the power steering fluid, which is essential for the system's operation. The rotary valve directs the fluid to either side of the piston, allowing for smoother and more responsive steering. The cylinder and piston work together to amplify the driver's steering input, making it easier to turn the steering wheel.

In contrast, the other options list components that are related to different automotive systems entirely. For instance, the first option mentions the battery, alternator, and starter, which are part of the vehicle's electrical starting system. The third option includes a fuel pump, spark plugs, and carburetor, which pertain to the fuel system and engine operation. Lastly, the fourth option lists brake pads, rotors, and calipers that are associated with the braking system. Therefore, option B accurately identifies the components specifically involved in the power steering system.
