In the Argand plane, the modulus of a complex number is its distance from the:
AThe origin
BThe real axis
CThe y-axis
DThe unit circle
Answer & Solution
Correct answer: A. The origin
1. The complex number x plus iy sits at the point P with coordinates x and y.
2. Its modulus is a length measured in the plane.
3. That length runs from P to the origin O.
