Solution
The correct option is A 1 3 2
Above the dredge line, the pressure is active on the back of the wall. Near the embedded end the pressure on the back of the wall will be passive as the wall moves towards the fill.
The retaining wall made of masonry is gravity retaining wall. If the wall is founded on rock there will not be any stretching of soil mass so earth pressure conditions will be at rest. Similarly on a compressible clay active earth pressure conditions will develop.
