The cross-section of a reflecting surface is represented by the equation `x^2 + y^2 = R^2` as shown in the figure. A ray travelling in the positive x direction is directed toward positive y direction after reflection from the surface at point M. The coordinate of the point Mon the reflecting surface is

A

(A) `((R )/(sqrt(2)),(R )/( sqrt(2)))`

B

(B) `(-(R )/(2),-(R )/( 2))`

C

(C) `(-(R )/(sqrt(2)),(R )/( sqrt(2)))`

D

(D) `((R )/(sqrt(2)),-(R )/( sqrt(2)))`
