The correct answer is:
$\left(2, \frac{\pi}{4}\right)$
Since, $Q$ is the point for which $P Q$ is bisected perpendicularly by the initial line $(X$ -axis). Therefore, $Q$ will be the image of $P$ in $X$ -axis
$\therefore$ Coordinates of $Q$ is $(2, \pi / 4)$
$\therefore$ Coordinates of $Q$ is $(2, \pi / 4)$
