Answer:  The correct option is

(C) x=50; y=50.

Step-by-step explanation:  Given that in the game of miniature golf, the ball bounces off the wall at the same angle it hit the wall as shown in the figure.

In the diagram, the ball hits the wall at a 40 degree angle.

We are to find the values of x and y.

From the figure, we note that

x^\circ+40^\circ=90^\circ\\\\\Rightarrow x+40=90\\\\\Rightarrow x=50.

Since the ball bounces off the wall at the same angle it hit the wall, so we must have

90^\circ-y^\circ=40^\circ\\\\\Rightarrow 90-y=40\\\\\Rightarrow y=90-40\\\\\Rightarrow y=50.

Thus, the required values of a and y are 50 and 50.

Option (C) is CORRECT.
