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.
