No, the friction coefficient of THE homogeneous soil is constant so is proportional ON height.

Lateral earth pressure is horizontal earth pressure.
We know k is lateral pressure/vertical pressure;
K= 1- sin(fi) /1+sin(fi)
Where fi is angle of internal friction.
Kwh is pressure intensity.
And o.5kwh2 is total pressure per metre length.
Hence lateral pressure proportional to the angle of internal friction.

I think B is correct because the lateral pressure is depends on height or point of application of pressure on the retaining wall.

In the question they asked lateral earth pressure not total pressure so, pressure p=co-efficient (k) *vertical stress (unit weight of soil (&gama;) * depth of soil).
From this equation, Pressure P is proportional to both K and depth of soil. Hence option B and D are correct.
From this equation, Pressure P is proportional to both K and depth of soil. Hence option B and D are correct.

C is right because lateral pressure means here total pressure.

It depends upon internal friction (because "ka" depends upon the angle of int friction) +it is proportional to square of depth, so both are right.

@Karan Panjabi.
Your formula is for total force not for pressure and formula for pressure is k * w * h.

I think B is the right answer.
Karan Panjabi said:

The Correct option is C.
Because P = 0.5 * kwh^2 , so there is no relation with the internal friction.
Because P = 0.5 * kwh^2 , so there is no relation with the internal friction.
