Zeolite comes under which group of silicates?

Answer: Option B

Zeolites are microporous, three-dimensional crystalline solids of aluminium silicate. Zeolites have small openings of fixed size in them which allow small molecules to pass through them easily but larger molecules cannot pass through them, that is why they are also called molecular sieves.
Zeolites come under the group of Tectosilicates, these are framework silicates that have a three-dimensional framework silicate tetrahedral with SiO₂ or a 1 : 2 ratio.
