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

B is correct, they not mentioned about total pressure in that case answer is C, but they gave answer D don't know how it proportional internal friction, but may be possible.

I think C is correct bacause it is not total pressure only lateral pressure.

C must be the answer.

The given answer is correct. Because in the formula 'h' means height of the soil retained by the wall but the alternatives says only the height of the soil.

Answer B is correct.

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.

Very nice, Thanks @Avinash.

It is independent of the depth option B was wrong it depend upon the internal friction and cohesion only.

Lateral pressure =kwh where w=unit wt.
But force=.5kwh^2.
But force=.5kwh^2.
