MCQ
Which axis is known as real axis in argand plane?
  • ✓
    x - axis
  • B
    y - axis
  • C
    z - axis
  • D
    any axis
✓

Answer

Correct option: A.
x - axis
The plane having a complex number assigned to each of its point is called the
complex plane or the Argand plane. When (x + y i) is plotted in argand plane, x-axis is real axis.
