Let

{z_1}

be a complex number with

\left| {{z_1}} \right| = 1

and

{z_2}

be any complex number, then

\left| {\frac{{{z_1} - {z_2}}}{{1 - {z_1}{z_2}}}} \right|

is equal to

View answer and explanation

Correct option: B

Option B (1) is correct because the modulus of the given expression simplifies to 1 using the property that |z1| = 1.
