Following are the statements related to the stress paths in a triaxial testing of soils: P. If σ₁ = σ₃, the stress point lies at the origin of the p-q plot. Q. If σ₁ = σ₃, the stress point lies on the p-axis of the p-q plot. R. If σ₁ > σ₃, both the stress points p and q are positive.

For the above statements, the correct combination is
