A two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane is as the polar coordinate.

The polar coordinate standard form is;

$\rm x = rcos \theta \\\\\ y= rsin \theta$

The value of the r is the resultant of the coordinate;

$\rm r= \sqrt{2^2+(-2\sqrt{3})^2 } \\\\r= 4$

The angle is found as ;

$\theta = tan^{-1}(\frac{y}{x}) \\\\ \theta = tan^{-1} \frac{-2\sqrt{3} }{2} \\\\ \theta = -60^0$

$x= rcos \theta \\\\ x= 4 cos(-60) \\\\ x= rcos \theta \\\\ x= 4 cos [-\frac{\pi}{3} ]\\\\ \rm y = r sin \theta \\\\ y= 4 sin [-\frac{-\pi}{6}]$

Hence the polar coordinates of the rectangular coordinates are (4,5π/3)Option D is correct.
