Following are the statements related to the stress paths in a triaxial testing of soils:

- If $\sigma_1 = \sigma_3$, the stress point lies at the origin of the $p-q$ plot
- If $\sigma_1 = \sigma_3$, the stress point lies on the $p$-axis of the $p-q$ plot
- If $\sigma_1 > \sigma_3$, both stress points $p$ and $q$ are positive

For the above statements, the correct combination is

- P – False; Q – True; R – True
- P – True; Q – False; R – True
- P – False; Q – True; R – False
- P – True; Q – False; R – False
