Solution

The correct option is B fore finger
According to Fleming's left-hand rule, one needs to stretch the thumb, forefinger, and middle finger of the left hand such that they are mutually perpendicular. If the first finger points in the direction of the magnetic field and the second finger in the direction of the current, then the thumb will point in the direction of motion or the force acting on the conductor.
