The radius of a circle C1 is thrice the radius of another circle C2 and the centres of C1 and C2 are (1,2) and (3,−2) respectively. If they cut each other orthogonally and the radius of the circle C1 is 3r, then the equation of the circle with r as radius and (1,−2) as centre is

x2+y2−2x+4y−3=0
x2+y2−2x+4y+7=0
x2+y2−2x+4y−7=0
x2+y2−2x+4y+3=0
