Express the complex number $z=-3\sqrt[\phantom{2}]{?}33i$ in polar form $r(cosisin).$

Select the correct answer below:

$12(cos(\frac{4}{3})isin(\frac{4}{3}))$

$12(cos(\frac{11}{6})isin(\frac{11}{6}))$

$12(cos(\frac{5}{6})isin(\frac{5}{6}))$

$6(cos(\frac{4}{3})isin(\frac{4}{3}))$

$6(cos(\frac{5}{6})isin(\frac{5}{6}))$

$6(cos(\frac{11}{6})isin(\frac{11}{6}))$
