The answer to your question is the letter a. (1, 3)

Step-by-step explanation:

Equation

                     (x - 1)² + (y - 3)² = 9

The Standard form of the circle

                     (x - h)² + (y - k)² = r²

In the standard form of the circle, the center is the letters (h, k) and the radius is r.

So, for this problem, the center is  h = -1  and k = -3, but there is a rule that says that we must change the signs, so the center is

                                                                                        (1, 3)
