Answer is option A

So the r.v are represented as the bottom(base) and left side of a square. The entire area sums up to 1 (pdf sums to 1 when integrated over the entire range). Inside this, draw a quarter circle which represents x^2 + y^2 = 1. Now we want the probability represented by the area outside, ie to the right of the circle. So this is just 1 - Pi/4
