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

But ranking theory not considered friction.
Only Coulomb theory considered friction.
So how can say that [D] answer right?

Correct option is (B) i.e. Lateral pressure on the retaining wall is *directly proportional to the depth of the soil*.

As we know,
P = 0.5 kwh^2.
From above P is directly proportional to square of height. So I think option C is right.
P = 0.5 kwh^2.
From above P is directly proportional to square of height. So I think option C is right.

The lateral earth pressure act at h/3 from toe of the wall, and which is p = 0.5*kh^2* unit weight. So answer is C.

P=1/2ka γ h^2.
So, lateral earth pressure is directly proportional to the square of the depth of the soil.
So, lateral earth pressure is directly proportional to the square of the depth of the soil.

Lateral Pressure proportional to depth. If it is lateral Pressure force it is proportional to Square of depth.

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

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

I think internal friction remains as a constant. When depth of soil increases, pressure also increases.
