If the radical centre of the given three circles x2+y2=1,x2+y2−2x−3=0 and x2+y2−2y−3=0 is C(α,β) and r is the sum of the radii of the given circles, then the circle with C(α,β) as centre and r as radius is

[TG EAPCET 14 May 2023 Shift 1]

(x−1)2+(y−1)2=2
(x−1)2+(y+1)2=4
(x−2)2+(y−2)2=25
(x+1)2+(y+1)2=25
