Correct option is A
In
general shear failure, a continuous failure surface develops between the
edge of the footing and the
ground surface. This type of failure is characterized by a well-defined shear zone and typically occurs in dense or stiff soils. The soil beneath the footing reaches its maximum bearing capacity, and failure propagates upward and outward, causing a bulging or heaving of the soil around the footing. This leads to a sudden and noticeable displacement at the ground surface.
