Which function demonstrates better reusability?

The function that demonstrates better reusability is the one that allows for more flexibility and customization across various scenarios. In this case, the function that specifies parameters such as position (x, y), dimensions (width, height), and an additional property (color) offers a wider range of applications.

A function like drawRectangle not only performs a specific task—drawing a rectangle—but also accepts inputs that modify its behavior for different contexts. For instance, by changing the parameters, you can easily draw rectangles of any size, at any location, and in any color. This versatility makes it applicable in multiple situations without needing to redefine or create new functions for each rectangle variation.

Other options do not provide the same level of customization. For example, drawing a simple shape or clearing the canvas is limited in scope and does not allow for numerous variations based on different inputs. The addCircle function also provides a degree of reusability, but it is more specific compared to drawRectangle, which can cover more ground by allowing for different forms and colors of rectangles in various drawings.
