In the ionic compound,AB the ratio ${\mathrm{r}}_{{\mathrm{A}}^{+}} : {\mathrm{r}}_{{\mathrm{B}}^{−}}\text{is }0.414$ Indicate the correct statement of the following:

Anions form close packing and cations occupy precisely half of the tetrahedral voids

Anions form close packing and cations fit into the octahedral voids loosely

Anions form close packing and cations occupy precisely all the octahedral voids

Cations form close packing and anions exactly fit into the octahedral voids
