Two dielectric materials A and B exhibit both ionic and orientational polarizabilities. The variation of their susceptibilities $$\chi \left( { = {\varepsilon _r} - 1} \right)$$ with temperature T is shown in the figure, where $${\varepsilon _r}$$ is the relative dielectric constant. It can be inferred from the figure that

B

A is more polar and it has a higher value of ionic polarizability than that of B

C

B is more polar and it has a higher value of ionic polarizability than that of A

D

B is more polar and it has a smaller value of ionic polarizability than that of A
