A Dipole Antenna Is Located at the Origin with Its $\circ$

A dipole antenna is located at the origin with its axis along the z-axis.As the antenna's electric current oscillates up and down the z-axis,polarized electromagnetic radiation travels away from the antenna along the positive y-axis.What is a possible direction of the radiation's oscillating magnetic field at point y=10m on the y-axis?

A) x-direction
B) y-direction
C) z-direction
D) 45 ^$\circ$ between the positive x- and positive y-directions
E) 45 ^$\circ$ between the positive x- and positive z-directions
