If the electric field of an electromagnetic wave is given by e(r, t) = (ie, + je, )e.-); i and are mutually orthogonal unit vectors both being perpendicular to

if the electric field of an electromagnetic wave is given by E(r, t) = (iE, + jE, )e.-); i and are mutually orthogonal unit vectors both being perpendicular to k and E, and E, are two real numbers, then the electromagnetic wave is/are not 2 (A) Plane polarized (B) Circularly polarized (C) Elliptically polarized (D) Unpolarized
