If z `in` C, which of the following relation(s) represents a circle on an Argand diagram? (where,`i=sqrt(-1)`)

Locate the point representing the complex number z on the Argand diagram for which |i-1-2z| gt 9 .

If z = 3 + 5i then represent the z, bar z, - z, - bar z in Argand's diagram.

If centre of a regular hexagon is at origin and one of the vertices on Argand diagram is 1+2i, where i=sqrt(-1) , then its perimeter is

If centre of a regular hexagon is at origin and one of the vertices on Argand diagram is 1+2i, where i=sqrt(-1) , then its perimeter is

If z = 3 + 5i, then represent z, bar z , -z, - bar z in Argand's Diagram.

The region represented by inequalities arg(z) =1 in the argand diagram is given by

If z=x+iy, where i=sqrt(-1) , then the equation abs(((2z-i)/(z+1)))=m represents a circle, then m can be

If z=x+iy, where i=sqrt(-1) , then the equation abs(((2z-i)/(z+1)))=m represents a circle, then m can be

If z=x+iy, where i=sqrt(-1) , then the equation abs(((2z-i)/(z+i)))=m represents a circle, then m can be
