Ok so remember tha tdividining by 0 is undifnined
therfor
4/(5x)
if x=0 then it is undifined
Equation of a circle in standard form with center (h,k) and radius r is given by :

In the given question the center of circle is lying on y axis so h=0 .Radius r=3 Substituting these values in the equation of circle we have:

Expanding we have :

Subtracting 9 both sides

Comparing this with the equation of circle in general form
A=1,B=1,C=0
If D=-8 then E=7
So option C is the right answer
