In figure, there is conducting ring having resistance `R` placed in the plane of paper in a uniform magnetic field `B_(0)`. If the rings is rotating in the plane of paper about an axis passing through point `O` and perpendicular to the plane of paper with constant angular speed `omega` in clockwise direction, then
A. Point `A` will be at higher potential than `O`.
B. The potential of point `B` and `C` will be same.
C. The current in ring will be zero.
D. The current in the ring will be `(2B_(0) omega. r^(2))/(R)`.
