In the closest packing of atoms
Note: OV stands for Octahedral voids and TV stands for Tetrahedral voids.

Options:

Answer:

Solution:

For a given radius of anion $(r_{-})$
Radius ratio for OV and TV is as follows
${(\frac{r_{\oplus}}{r_{-}})}_{O V} > {(\frac{r_{\oplus}}{r_{-}})}_{T V}$
$[_{F o r T V, \frac{r_{\oplus}}{r_{-}} = 0.225 - 0.414}^{F o r O V, \frac{r_{\oplus}}{r_{-}} = 0.414 - 0.732}]$
Hence, size of OV is larger than that of TV.
