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.

@Susmita, you are correct. Answer is B is also possible. This depends on what theory you use for calculating the lateral earth pressure. Either Rankine or Coulomb.

Option E None of the above is the correct one.
The Lateral earth pressure is directly proportional to the depth of the soil because;
P = KwH.
P proportional H.
The Lateral earth pressure is directly proportional to the depth of the soil because;
P = KwH.
P proportional H.

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.

Lateral earth pressure means horizontal pressure. So it is Ka*H which is answer b. But if it was asked total earth pressure then answer would be C.

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.

The magnitude of the lateral earth pressure depends upon the movement of the retaining wall relative to the backfill and upon nature of the soil.

p = kwh. So p is proportional to h directly. And k, that's (1-sinφ)/(1+sinφ).
How on the earth proportional to internal friction φ?
How on the earth proportional to internal friction φ?

I think answer B is also right, cause from the formula we know that p=k*y*z. So lateral earth pressure is also proportional with z means height.

I think this answer is not correct because the equation is 1/2k^h^2 that's why earth pressure is directly proportional to the square of height.
