I think C is the wrong answer.

E is the correct answer.
t = CV * Tv/d'2.
Cv = k/Av * density.
t = CV * Tv/d'2.
Cv = k/Av * density.

"av" is proportional to "mv", "mv" is inversely proporitonal to "Cv", "Cv" is inversely proportional to "t".
So, "t" increases with "av" increased.
So, "t" increases with "av" increased.

Option A is absolutely correct.
Compressibility means av (coefficient of compressibility) "av" is propertional to "mv", "mv" is inversely proporitonal to "Cv", "Cv" is inversely proportional to "t".
So as av increase mv increase and so cv decreases leading to increase of t i.e consolidation time.

If you see the formula as mentioned above, E is correct.

If soil compresses continuously then the consolidation process required to remove air from soil, therefore, consolidation time increase.
If soil doesn't compress then consolidation not required.
If soil doesn't compress then consolidation not required.

Give an explanation for the answer.

I think Option A is not correct. Then how it would be D?

All options are correct.
t = (Tv*d^2*Yw*av)/(k*(1+e)).
t = (Tv*d^2*Yw*av)/(k*(1+e)).
