Solution
The correct option is C Up, out of the plane
The direction of the force experienced by the wire can be determined using fleming's left hand rule. The forefinger points to the direction of the magnetic field. The middle finger points in the direction of the current. The thumb gives the direction of force or motion acting on the conductor.
The direction of current is in the direction of the motion of positive charges. Hence, the direction of force is out of the plane.
Hence, option C is the correct answer.
