Find the center and radius of the circle whose graph is shown. Write the standard form of the equation of the circle.
A. r = 4; (h, k) = (-4, 1); (x - 4)2 + (y + 1)2 = 16
B. r = 2; (h, k) = (-4, 1); (x - 4)2 + (y + 1)2 = 4
C. r = 2; (h, k) = (-4, 1); (x + 4)2 + (y - 1)2 = 4
D. r = 4; (h, k) = (-4, 1); (x + 4)2 + (y - 1)2 = 16
