Final answer:
When the mouse is pressed while running the code, the circle gets bigger.
Step-by-step explanation:
When the mouse is pressed while running the code, the circle gets bigger. This is because the line of code c.radius = c.radius + 10 increases the radius of the circle by 10 units each time the mouse is pressed. Therefore, the circle will gradually grow larger as the mouse is pressed multiple times.
