From the below figure it is clear that the center of the given circle is (4,5).
The standard form of a circle is
where, (h,k) is center of the circle and r is radius.
We need to find the equation of a circle which represents the same center as the circle shown but with a radius of 2 units.
Substitute h=4, k=5 and r=2 in the above equation.
The required equation is .
Therefore, the correct option is B.
