Parabola

Answer the following by appropriately matching the lists based on the information given in the paragraph.
Let the circles C1:x2+y2=9 and C2:(x−3)2+(y−4)2=16 intersect at the points X and Y. Suppose that another circle C3:(x−h)2+(y−k)2=r2 satisfies the following conditions :
(i) Centre of C3 is collinear with the centres of C1 and C2
(ii) C1 and C2 both lie inside C3, and
(iii) C3 touches C1 at M and C2 at N
Let the line through X and Y intersect C3 at Z and W, and let a common tangent of C1and C3 be a tangent to the parabola x2=8αy
