Av = e1-e2 / q1-q2
if q decrease then the coefficient of compressibility (Av) increases. and void ratio e = e1 - e2 decreases due to increase in stress
If Av increases then Mv = Av/1+e, Mv also increases.
then the permeability K = Cv . Mv . Yw if Mv increases then K also increases.
if q decrease then the coefficient of compressibility (Av) increases. and void ratio e = e1 - e2 decreases due to increase in stress
If Av increases then Mv = Av/1+e, Mv also increases.
then the permeability K = Cv . Mv . Yw if Mv increases then K also increases.

Answer D is correct.
"When stress decreases void ratio" i.e. if stress has to decrease void ratio stress should be increased.
If stress increases mv decreases as it is inversely proportional to stress increase. As k and mv are directly proportional, k also decreases if mv decreases.
"When stress decreases void ratio" i.e. if stress has to decrease void ratio stress should be increased.
If stress increases mv decreases as it is inversely proportional to stress increase. As k and mv are directly proportional, k also decreases if mv decreases.

Answer D is absolutely correct.
The option states that WHEN STRESS DECREASES VOID RATIO, means because of stress, the void ratio has decreased so, K & Mv also decreases.

When stress decreases void ratio, volume decreases and hence flow of water through soil (permeability) also decreases.

I think all 3 components increases as stress are decreases.

Decreases or increases? In deep confusion!

I think that all will increase.

All the 3components increases.

Correct, Thanks @Nadeem Qadir.

Yes, it should be "increases".
