How is the teleport function triggered in the Teleporting Ball program?

The teleport function in the Teleporting Ball program is triggered through a mouse click event. This means that when the user interacts with the program by clicking their mouse, the function executes, causing the ball to teleport to a new position. This interaction creates an engaging dynamic, allowing users to directly influence the behavior of the ball, which enhances their experience with the program.

The other choices involve different methods for triggering actions within a program. Triggering through a timer could imply that the function is executed at set intervals, which does not apply here. Automatically triggering at start would mean the ball teleports once the program begins, which would not provide user interaction. Triggering when the ball hits a wall suggests a reaction to an event based on collision detection, which is also not how the teleport function is designed to operate in this specific context.
