The normal boiling point of a liquid ‘X’ is 400K. Which of the following statement is true about the process ${\text{X}}_{\left(\text{l}\right)}\to {\text{\hspace{0.17em}X}}_{\left(\text{g}\right)}$

at 400°K (1 atm) system is at equilibrium, hence $\Delta G=0$

At 400K 2 atm pressure liquid does not boil and it is non spontaneous process $\left(\text{ΔG\hspace{0.17em}=\hspace{0.17em}+\hspace{0.17em}ve}\right)$

At 400K and 0.1 atm pressure, liquid boil and it is spontaneous hence $(\Delta G=-ve)$
