Center of given circle is (h,k)= (5,-3)
Option A is correct.
Step-by-step explanation:
We need to find the coordinates of the center of the given circle: 
The standard equation of circle is:

Where (h,k) is the center of circle and r is the radius of circle.
Now comparing the given equation with standard equation to find h and k

Making it equivalent to standard equation:

By comparing, the value of h is 5 and k is -3
Hence center of given circle is (h,k)= (5,-3)
Option A is correct.
