Two metallic rings A and B, identical in shape and size but having different resistivities $$\rho_A$$ and $$\rho_B$$, are kept on top of two identical solenoids as shown in the figure below. When current I is switched on in both the solenoids in identical manner, the rings A and B jump to heights $$h_A$$ and $$h_B$$, respectively, with $$h_A > h_B$$. The possible relation(s) between their resistivities and their masses $$m_A$$ and $$m_B$$ is (are)

$$\rho_A$$ > $$\rho_B$$ and $$m_A$$ = $$m_B$$

$$\rho_A$$ < $$\rho_B$$ and $$m_A$$ = $$m_B$$

$$\rho_A$$ > $$\rho_B$$ and $$m_A$$ > $$m_B$$

$$\rho_A$$ < $$\rho_B$$ and $$m_A$$ < $$m_B$$
