The correct answer is: possible at high temperature
Given, $\Delta S=+$ ve and $\Delta H=+$ ve $($ For endothermic reaction)
Now, $\quad \Delta G=\Delta H-T \Delta S$
For a reaction to be spontaneous, $\Delta G$ should be -ve which is possible only at high temperature i.e., when $T \Delta S>\Delta H$.
