Kaolinite has gibbsite sheets with aluminium their centre. Since hydrogen bond is involved it is extremely difficult to separate the layers, therefore kaolinite is stable and water is unable to penetrate b/w the layers hence kaolinite shows no swelling when wetting.

Kaolinite - no swelling ( China clay),
Illite - little swelling,
Montmorillonite - high swelling (B.C Soil).

So answer for given question must be A.

In illite_ The space between individual clay crystals is occupied by poorly hydrated potassium cations which are responsible for the absence of swelling.

In illite_ The space between individual clay crystals is occupied by poorly hydrated potassium cations which are responsible for the absence of swelling.

Yes, A is correct answer.

Mite is an organic soil & act as a decomposer in soil & Kaolinite behaves as a no swelling properties so the correct answer is Kaolinite.

Kaolinite is stable mineral causes no dwelling & shrinkage. So the answer should be kaolinite.

The answer must be kaolinite.
