Which of these best describes
'Liquid Limit'?
timer

A
The water content at which the soil stops acting as a plastic and starts acting as a solid
B
The water content at which the soil no longer displays permanent deformation and simply fractures when shearing stresses are applied
C
A cohesive soil with an extremely high water content – behaves as a liquid with continual deformation
D
The water content at which the soil stops acting as a liquid and starts acting as a plastic solid
