Select all true statements.

In triaxial loading:
When the water pressure increases, there is a transition from ductile to brittle
behavior.

1-The confining pressure (03) is progressively increased to break the sample
subjected to uniform principal stresses (o1 = 02).

2- When the confining pressure decreases, the behavior changes from strain-
softening to strain-hardening.

 3-When initially loaded, the rock specimen compresses and then begins to dilate
as a result of internal fracturing.
