In the standard (x, y) coordinate plane, the center of a circle lies in quadrant III. If the circle is tangent to the x-axis and the y-axis, which of the following is an equation for the circle?
（A）(x + 4)2 + (y + 4)2 = 4 （B） (x - 4)2 + (y - 4)2 = 4 （C） x2 + (y - 4)2 = 16 （D） (x + 4)2 + (y + 4)2 = 16 （E） (x + 4)2 + (y - 4)2 = 16
Correct Answer: D
