Relative permittivity and permeability of a material are $\varepsilon_r$ and $\mu_r$, respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

Question

( A ) $\varepsilon_r$= 0.5, $\mu_r$ = 1.5
( B ) $\varepsilon_r$= 1.5, $\mu_r$ = 0.5
( C ) $\varepsilon_r$= 0.5, $\mu_r$ = 0.5
( D ) $\varepsilon_r$= 1.5, $\mu_r$ = 1.5
