Which of the following best describes the purpose of an elevator's control panel?

The purpose of an elevator's control panel primarily revolves around facilitating floor selection and controlling the movement of the elevator. The control panel allows passengers to indicate their desired destination by selecting a specific floor, which then communicates with the elevator's system. This system interprets the input and operates the elevator accordingly, ensuring safe and efficient transport between floors.

In well-designed systems, control panels may also include additional features such as emergency buttons, indicators showing which floors the elevator is traveling to, and signs displaying relevant operational information. However, the core function remains the control of elevator movement and user interaction, making it essential for a smooth and user-friendly experience.
