S = z C /| z -1+ i |=1 represents

Options

  1. Aa circle with centre (-1,1) and radius 1 unit
  2. Ba circle with centre (1,2) and radius 5 units
  3. Ca circle with centre (1,-1) and radius 1 unit
  4. Dan ellipse with centre (1,-1)

Correct answer

C. a circle with centre (1,-1) and radius 1 unit

Step-by-step solution

Since |z-1+i|=1 |z-(1-i)|=1 So, S represent a circle with centre (1,-1) and radius 1
