Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 - 16x - 12y + 75 = 0
A. (x - 8)2 + (y - 6)2 = 25 center (8, 6), r = 5 B. (x + 8)2 + (y + 6)2 = 25 center (-8, -6), r = 5 C. (x - 8)2 + (y - 6)2 = 25 center (8, 6), r = 25 D. (x - 6)2 + (y - 8)2 = 25 center (6, 8), r = 5
