According to the Phase Diagram Given, Which of the Following

According to the phase diagram given, which of the following statements is INCORRECT?

A) At the temperature and pressure of point 1, W exists as a three-phase equilibrium system.
B) At the temperature of point 2, a pressure of 500 torr will cause W to liquefy.
C) If the system is maintained at the temperature of point 3 while pressure is decreased, more W will vaporize.
D) If W is maintained at the pressure of point 4 while the temperature is increased to 80°C, the liquid will vaporize.
E) The existence of liquid W at -40°C and 500 torr represents the metastable condition of "supercooling."
