Clay mineral with limited expansion

A. Vermiculite

B. Illite

C. Bentonite

D. Beidellite

Answer: Option A

Solution(By Examveda Team)

Clay mineral with the limited expansion is Vermiculite.
Vermiculites expand more than Kaolinite but much less than smectite. The cation exchange capacity (CEC) of vermiculite is higher than all other silicate clays because of the very high negative charge in the tetrahedral sheet.
