Solution

The correct option is D Some of the $S i O_{4}^{4 -}$ units are replaced by $A l O_{4}^{5 -}$ and $A l O_{6}^{9 -}$ ions in zeolites.
$A l O_{4}^{5 -}$ ion has nearly the same size as the $S i O_{4}^{4 -}$ ion and can replace the latter from silicates provided electrical neutrality is maintained.
