Solution

The correct option is B left handed elliptical
Ans : (d)

$\to E (z, t) = {^a}_{x} c o s (2 π \times 10^{7} t - 0.2 z) + {^a}_{y} 2 c o s (2 π \times 10^{7} t - 0.2 z + \frac{π}{2})$

$\Rightarrow$ Wave is travelling in ${^a}_{z}$ direction.

$\Rightarrow$ Wave has orthogonal components with unequal amplitudes and checking the time trace

$∴$ Wave is left hand elliptically polarized.
