Pick up the correct statement from the following:
The property of a soil that enables it to become stiff in a relatively short time on standing is called thixotropy
The ratio of shear strength in natural state to the remoulded shear strength under undrained conditions, is called degree of sensitivity.
The difference between the undisturbed shear strength and remoulded shear strength is known remoulding loss
The tendency of dense sand to expand on application of shearing load, is known as dilatancy
All the above.
