An electromagnetic wave polarized parallel to the z-axis travels positively along the x-axis.?
How can this wave best be detected using a straight wire antenna?
A. Orient the antenna parallel to the x-axis.
B. Orient the antenna parallel to the y-axis.
C. Orient the antenna parallel to the z-axis.
D. The antenna will work equally well for any of these orientations.
E. This wave cannot be detected with a straight wire antenna. A loop antenna must be used.

When we say an EM wave is polarised parallel to the z-axis, by convention it means the direction of the wave's electric field is parallel to the z-axis.
By having a straight wire parallel to the z-axis, conduction electrons will be free to oscillate backwards and forwards along the wire - which creates an oscillating emf (which is the signal).
