\left( {1 - i\sqrt 3 } \right)\left( {1 + i\sqrt 3 } \right)

View answer and explanation

Correct option: D

{240^0}

Option D (

{240^0}

) is correct because the argument of the complex number

\frac{{1 - i\sqrt 3 }}{{1 + i\sqrt 3 }}

is calculated to be

{240^0}

after rationalizing and finding the angle in the correct quadrant.
