Electrical resistance of certain materials, known as superconductors, changes abruptly from a nonzero value to zero as their temperature is lowered below a critical temperature $\mathrm{T}_{\mathrm{C}}(0)$. An interesting property of superconductors is that their critical temperature becomes smaller than $\mathrm{T}_{\mathrm{c}}(0)$ if they are placed in a magnetic field, i.e., the critical temperature $\mathrm{T}_{\mathrm{c}}$ (B) is a function of the magnetic field strength B . The dependence of $T_c(B)$ on $B$ is shown in the figure.
In the graphs below, the resistance R of a superconductor is shown as a function of its temperature T for two different magnetic fields $B_1$ (solid line) and $B_2$ (dashed line). If $B_2$ is larger than $B_1$ which of the following graphs shows the correct variation of R with T in these fields?
