Match the following columns:

Let (x, y) be such that

sin-1(ax) + cos-1(y) + cos-1(bxy) = π/2

Column I Column II
(A) If a = 1 and b = 0, then (x, y) (P) lies on the circle x2 + y2 = 1
(B) If a = 1 and b = 1, then (x, y) (Q) lies on (x2 - 1)(y2 - 1) = 0
(C) If a = 1 and b = 2, then (x, y) (R) lies on the line y = x
(D) If a = 2 and b = 2, then (x, y) (S) lies on (4x2 - 1)(y2 - 1) = 0
