Consider the radii 0.095 nm Na+,0.181 nm (CI-), 0.074 nm (Zn2+)0.184 nm S2−,0.068 nm Ti4+0.140 nm O2−,0.169nm(Cs+)Choose the correct option from among the following. (Use radius ratio rules)

A
Na⁺ ions are packed in octahedral holes between the planes of close-packed CI^-ions
B
${Zn}^{2 +}$ ions are packed in tetrahedral holes
C
${Cs}^{+}$ ions are packed in a simple cubic array of CI^-ions
D
All of these

Calculate the $\frac{r +}{r -}$ ratio to get the limiting ratio value and according to the table. All are correct.

Consider the radii 0.095 nm $({Na}^{+})$ ,0.181 nm (CI^-), 0.074 nm (Zn2⁺)0.184 nm $(S^{2 -})$ ,0.068 nm $({Ti}^{4 +})$ 0.140 nm $(O^{2 -})$ ,0.169nm(Cs⁺)Choose the correct option from among the following. (Use radius ratio rules)
