Answer:
Option 1:

Explanation:
We can observe the given graph to find the center and radius
By observing the graph we can conclude that the center of the circle is at
x = 3 and y = -2 which means the center is:
(h,k) = (3,-2)
Similarly the radius is 3 because the distance between the center and boundary of circle is 3 units.
So, r = 3
The standard form of equation of a circle is:

Putting the values of h,k and r

Hence, the correct answer is option 1 ..
