Okay, here we have this:

Considering the provided information, and that the form of the standard circle equation is (x-h)²+(y-k)²=r², where the centered at (h, k), and radius r, so replacing with the provided data, we obtain:

(x-h)²+(y-k)²=r²

(x-(-2))²+(y-(-3))²=(7)²

(x+2)²+(y+3)²=49

Finally we obtain that the correct answer is the first option
