Column II gives four situations in which three or four semi-finite current carrying wires are placed in x-y plane. The magnitude of the direction of current is shown in each figure. Column I gives statements regrading the x- and y- components of magnetic field at point P whose coordinates are (0,0,d). Match the statements in Column I with the corresponding figures in Column II.
