The standard equation of the circle may be determined through the expression, (x - h)² + (y - k)² = r² where h and k are the abscissa and ordinate of the center of the circle, respectively. r, on the other hand is the measure of the radius. Thus, it is important to know the radius and coordinates of the center. The answer is letter D.
