The temperature difference across two cylindrical rods \(A\) and \(B\) of same material and same mass are \(40^{\circ} \mathrm{C}\) and \(60^{\circ} \mathrm{C}\) respectively. In steady state, if the rates of flow of heat through the rods A and B are in the ratio \(3: 8\), the ratio of the lengths of the rods \(A\) and \(B\) is
- A \(1: 3\)
- B \(5: 3\)
