Two very long straight parallel wires, parallel to y-axis, carry currents 41 and I, along+y direction and-y direaction respectively. The wires are passes through the x-axis at the points `(d, 0,0)` and `(-d, 0,0)` respectively. The graph of magnetic field z-component as one moves along the x-axis from `x = - d` to `x = +d`, is best given by
