What is the value of $\Delta G$ for a water system in an environment at a temperature of $100 \ K$?
(C) The freezing point of water is $273 \ K$ at $1 \ \text{atm}$ pressure.
At $100 \ K$,the system is below the freezing point of water.
Since the temperature is below the phase transition temperature $(273 \ K)$,the process of freezing (liquid to solid) is spontaneous.
For a spontaneous process,the change in Gibbs free energy is negative,i.e.,$\Delta G < 0$.
