Solution

The correct option is A (a2+b2)(x2+y2)=2ab(bx+ay)

Equation of common chord,
s1s2=0
2ax2by=0
ax=by.....(1)
x=bya
Put x=bya in x2(yb)2=b2
b2y2a2+y22by=0
y(a2+b2)2b2=0
y=2ba2(a2+b2) and x=2ab2(a2+b2)
Equation of circle whose diametric ends are (0,0) and (2ab2a2+b2,2a2ba2+b2) is
x(x2ab2a2+b2)+y(y2a2ba2+b2)=0
(a2+b2)(x2+y2)=2ab(bx+ay)
