Answer: Option D
Solution (By Examveda Team)
Vermiculite is a hydrous phyllosilicate material that undergoes significant expansion when heated.Vermiculite is a 2 : 1 neutral clay, which means it has two tetrahedral sheets for every octahedral sheet. Vermiculite has a high cation-exchange capacity (CEC) at 100 - 200 Cmolc (P+)/Kg.
