Explanation:
B i think ........................
As per right hand thumb rule if we put our thumb of right hand along the current in the wire then curl of fingers will show the direction of magnetic field.
So here as we can see the fingers in the above case is curled such that in front position its showing towards right.
So the direction of magnetic field near the student in front position must be towards Right.
The lights will no longer work because the circuit will be cut
