Which of the following is the condition for a non spontaneous reaction at high temperature but spontaneous at low temperature?

 Change in Gibbs free energy equation

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

Where, $\Delta H$ is change in enthalpy and $\Delta S$ is change in .

$\Delta G=+ve$ for non-spontaneous

$\Delta G=0$ for equilibrium

$\Delta S>0,\Delta H<0$ for spontaneous.

When $\Delta H<0\text{ and }\Delta S<0\text{ then }\Delta G=-ve$ at low temperature and the reaction become spontaneous.

Therefore, option A is correct.
