Explanation

According to the current diagram, y° is larger than x°. But remember, the figures are not always drawn to scale and you are free to make changes provided you keep the information given as a constant. In this case, the constant is that PS = SR.

So keeping line PR the same, where PS = SR, move Q around to see what happens to x and y:

As you can see, it’s impossible to determine which angle is greater without having more information about point Q.

Hence option D is correct.
