Correct answer
B
Step-by-step explanation
Given R = {(P, Q) | P and Q are at the same distance from the origin}.
Then equivalence class of (1, 1) will contain al such points which lies on circumference of the circle of centre at origin and passing through point (1, 1).
i.e., radius of circle =
Required equivalence class of (S)
