Dissolution of ammonium chloride in water is an endothermic reaction, yet it is a spontaneous process. This is due to the fact that :

The correct option is D $\Delta$H is +ve, $\Delta$S is +ve and $\Delta$H < T$\Delta$S
$\Delta H>0$ (endothermic reaction)

Now, $\Delta G=\Delta H-T\Delta S$

For spontaneous process, $\Delta G<0$

Therefore, $\Delta G=\Delta H-T\Delta S<0$

But $\Delta H>0$

Therefore for $\Delta G$ to be negative, $\Delta S>0$ and $\Delta H<T\Delta S$.
