Solution

The correct option is C the field at R must be out of the plane of the paper
In circle $A,$ current is clockwise $,$ the field produced by it into the plane by Right hand Screw Rule $.$
Similarly $,$ in $B$ circle current is clockwise $,$ so field produced is out side the plane
Hence,
option $(C)$ is correct answer.
