MCQ

If $z$ is a complex number, then :

A
$|\text{z}|^2>|\text{z}|^2$
✓
$|\text{z}|^2=|\text{z}|^2$
C
$|\text{z}|^2<|\text{z}|^2$
D
$|\text{z}|^2\geq|\text{z}|^2$

✓

Answer

Correct option: B.

$|\text{z}|^2=|\text{z}|^2$

It is obvious that, for any complex number $z,$
$|\text{z}|^2=|\text{z}|^2$
