If $Z=1+i\sqrt{3}$ then match the following

Column – I	Column –II
A) Arg z	1) $-\frac{\pi }{3}$
B) Arg (iz)	2)$\frac{\pi }{3}$
C) $Arg\left(\overline{z}\right)$	3)$\frac{5\pi }{6}$
D) $Arg\left(i\overline{z}\right)$	$4)\frac{\pi }{6}$

$z=x+iy$

$Argz={\tan }^{-1}\left|\frac{y}{x}\right|ifx>0,y>0=\pi -{\tan }^{-1}\left|\frac{y}{x}\right|ifx<0,y>0$

$=-\pi +{\tan }^{-1}\left|\frac{y}{x}\right|ifx<0,y<0=-{\tan }^{-1}\left|\frac{y}{x}\right|ifx>0,y<0$
