If the close-packed cations in an `AB`-type solid gave a radius of `75` pm. What would be the maximum and minimum sizes of the anions filling the voids?

A

`r_("minimum")^(-) = 101.45, r_("maximum")^(-) = 303.3 pm`

B

`r_("minimum")^(-) = 105.45, r_("maximum")^(-) = 300.3 pm`

C

`r_("minimum")^(-) = 102.45, r_("maximum")^(-) = 333.3 pm`

D

`r_("minimum")^(-) = 98.4, r_("maximum")^(-) = 333.3pm`
