Solution
The correct option is C Solid → Gas
Along the constant pressure line of P=0.006, we have ice (solid H2O) on the left of the triple point, and steam (gaseous H2O) on the right.
Thus, as we increase the temperature from below Tp to above Tp, we observe a solid → gas phase transition, i.e., we see ice directly turning into gas without going through the water phase. Magical!
