If , then the locus described by the point in the argand diagram is a
circle
Explanation for the correct option.
Find the locus of point .
Let be a complex number, then the equation can be written as:
Now, square both sides.
So point is defined by the line and it is the equation of a circle.
So the locus described by the point in the argand diagram is a circle.
Hence, the correct option is B.
