Two gases \(A\) and \(B\) are filled at the same pressure in separate cylinders with movable pistons of radius \(r_A\) and \(r_B,\) respectively. On supplying an equal amount of heat to both the systems reversibly under constant pressure, the pistons of gas \(A\) and \(B\) are displaced by \(16~ \text{cm}\) and \(9~ \text{cm},\) respectively. If the change in their internal energy is the same, then the ratio \(r_A / r_B\)  is equal to:
1. \(\dfrac{2}{\sqrt{3}}\) 2. \(\dfrac{\sqrt{3}}{2}\)
3. \(\dfrac{4}{3}\) 4. \(\dfrac{3}{4}\)
