We always neglect constant for defining proportionality relationship. As here answers are more than one hence answer is none of above.

The critical Exit Gradient is Directly Proportional to Specific gravity and Inversely proportional to void ratio.

I = (G-1)/(1+e).

Directly proportional to G and also inversely proportional to e.

Both C & D are correct for this question.

it's not quick sand condition given is seepage exit gradient.

Exit gradient = (delta h/Nd) * (1/delta L).

Vivek said:   10 years ago
Directly proportional to G-1. And inversely proportional to 1+e. That's why answer (E).

Paras Nayyar said:   10 years ago
Since 1 is constant so i is directly proportional to G and inversely proportional to e.

Right @Dipu Bunku Rose.

It's critical exit gradient, not critical hydraulic gradient.

Pramod jaiswal said:   4 years ago
Anyone, explain the difference of the critical hydraulic gradient and exist gradient.

Ajay said:   5 years ago
Seepage velocity = velocity gradient/porosity.

So, Answer E is correct.

And is right.

Because exit gradient is headloss divided by length.
