Dear Student,Solution) Let ax=by=cz=k⇒ ax=k ⇒a=k1x
(i)⇒by=k⇒b=k1y (ii)⇒cz=k⇒c=k1z
(iii)As, it is given that, b2=ac                           ⇒ k1y2=k1x
k1z {Using i,ii and iii}                           ⇒ k2y=k1x+1z          {In case of multiplication, when bases are same, powers are added}                         Now, on comparing both sides, we get,                          ⇒2y=1x+1z                         ⇒2y=z+xzx                         ⇒y=2zxz+x=(A) option Regards!
