`A^+B^-` shows rock salt type arrangement. Edge length of unit cell is `6overset{o}{A}`. If radius of `A^+` is `1overset{o}{A}` then incorrect option is:
| A. |
Distance between nearest cations is `3sqrt2 overset{o}{A}` |
| B. |
Number of nearest cations from a given cation are 8 |
 |
| C. |
Number of cations and anion each are 4 per unit cell |
| D. |
On removing all the anions a FCC unit cell made by `A^+` ions is observed |
