Question

​​The triple point $\left(T_{l}, P_{l}\right)$ is shown in a schematic phase diagram (pressure $(\mathrm{P})-$ temperature $(\mathrm{T})$ plot) for one component system. $\text{G}_s$, $\text{G}_L$ and $\text{G}_v$ are the free energies of solid, liquid and vapor, respectively. At a constant pressure, $P_{I}$, the correct free energy $(\mathrm{G})$ versus temperature $(\mathrm{T})$ plot is

• A.
• B.
• C.
• D.
