Choose one incorrect statement about the Triaxial Compression Test. A sketch is a

Mohr$-$Coulomb failure curve obtained from a soil sample.

The deviator stress is one of principal stresses along the vertical axis.

The Mohr$-$Coulomb failure criterion is based on the assumption that cohesion

and internal friction may be combined in a single component of shearing stress.

The shear resistance $($inherent stability$)$ of soil is represented by the Mohr$-$

Coulomb failure criterion.

The goal of the Triaxial Compression Test is to determine the shear strength of a

soil under the lateral pressure.
