A

the unit disc with its centre at `z=0`

B

the exterior of the unit circle with its centre at `z=0`

C

the inerior of a square of side `2` units with its centre at `z=0`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B

`(b)` `|2z-3i|^(2) lt |3z-2i|^(2)`
`:. 4x^(2)+(2y-3)^(2) lt 9x^(2)+(3y-2)^(2)`
`:.x^(2)+y^(2) gt 1`
`:. |z|^(2) gt 1`
