A coaxial cable made up of two conductors. The inner conductor is solid and is of radius R1 and the outer conductor is hollow of inner radius R2 and outer radius R3. The space between the conductors is filled with air. The inner and outer conductors are carrying currents of equal magnitudes and in opposite directions. Then the variation of magnetic field with distance from the axis is best plotted as

In the figures given show four different sets of wires that cross each other without actually touching. The magnitude of the current is the same in all four cases and the directions of current flow are as indicated. For which configuration will the magnetic field at the centre of the square formed by the wires be equal to zero?
