Dear Student,
If for a particular event or reaction, the change in gibbs free energy is negative lr less than zero, then the reaction or event is said to be spontaneous.
Now, the melting of ice is spontaneous at above 273K temperature and 1 atm pressure.
So, melting of ice at 2 atm pressure and 273 K is spontaneous.
Now, for boiling water, above 1 atm pressure and 373 K is called spontaneous.
So, boiling water at 2 atm pressure and at 373K is called spontaneous.
Therefore the options will be 1 and 4.
