Question

If $z subscript 1 end subscript$ , $z subscript 2 end subscript$ are conjugate complex numbers and $z subscript 3 end subscript$ , $z subscript 4 end subscript$ are also conjugate, then arg $open parentheses fraction numerator z subscript 3 end subscript over denominator z subscript 2 end subscript end fraction close parentheses$ is equal to

arg $(\frac{z_{1}}{z_{4}})$
arg $(\frac{z_{4}}{z_{1}})$
arg $(\frac{z_{2}}{z_{4}})$
arg $(\frac{z_{1}}{z_{3}})$

The correct answer is: arg $open parentheses fraction numerator z subscript 1 end subscript over denominator z subscript 4 end subscript end fraction close parentheses$
