What is the purpose of the target function in the provided code?

The purpose of the target function in the provided code is to draw horizontal and vertical lines at the mouse's coordinates. When the function is invoked, it typically takes the current position of the mouse pointer and uses that information to draw lines on the screen, effectively creating a crosshair effect or a coordinate grid. This visualization helps in understanding the relationship between the current mouse position and the drawing space.

The other choices do not align with the function's expected behavior as described. For instance, removing lines or resetting coordinates does not involve drawing at the mouse's location, nor does creating a Circle object directly relate to the primary function of drawing lines at specified coordinates. The focus of the target function is indeed on the visual representation of lines crossing at the point where the mouse is clicked or hovered over, confirming that drawing these lines is its main objective.
