Which engages a toothed rack for lift movement?

Explanation:
The main idea is how a pinion gear interacts with a toothed rack to create linear motion for the lift. The rack is a straight bar with teeth, and the pinion is a small circular gear that meshes with those teeth. When the pinion rotates, its teeth push against the rack teeth, converting rotational movement into linear movement along the rack. This drives the lift up or down. The whole system can be described as a rack-and-pinion drive, but the component that actually engages the rack and moves it is the pinion gear. The other options refer to parts or concepts that aren’t the engaging element of the rack.
