    you can notice that we are given the double angle formula for tan 2x so we can say that \[\tan 2x = \sqrt{3}\] we know that tan is only positive in the first and third quadrant on solving this \[\tan^{-1} \sqrt{3} = \frac{ \Pi }{ 3 }\] then the solution will be \[\frac{ \Pi }{ 6 }\]and its nPi multiplies so it will be d.
