Which function is designed with better reusability practices?

The function designed with better reusability practices includes parameters for position, size, and color, allowing it to be used in a wider variety of situations. By having the parameters x, y, radius, and color, this function can draw circles in different locations, sizes, and colors without needing to rewrite or duplicate code for each specific instance.

Reusability is enhanced because developers can easily call this single function with different arguments to create diverse visual outputs, making it more adaptable in various contexts. For example, if you want to incorporate different colored circles in a graphic or animation, you can do so by changing just the color argument while keeping the rest of the function intact. This design reduces redundancy and encourages cleaner, more maintainable code.

In contrast, options that limit the number of parameters, like those that only include position and radius or only position and color, are less flexible, as they restrict the function's application in different scenarios where more attributes might be necessary. Therefore, the function that incorporates all these variables exemplifies the best reusability practices in programming.
