What would happen, when the

following  code snippet runs:

for i in bricksR:
        if i.collidepoint(ball.x,ball.y):
            bricksR.remove(i)
            ballx=-ballx
            bally=-bally
            score+=3

Q.2

The x and y coordinates of the ball will get reset to 0. Score will get incremented by 3.

A

C

The x and y coordinates of the ball will get updated 10. Score will get incremented by 2.
