For a balanced reversible gaseous reaction: $A_{(g)}+B_{(g)} \rightleftharpoons 3 C_{(g)}+2 D_{(g)}$

Question

For a balanced reversible gaseous reaction: $A_{(g)}+B_{(g)} \rightleftharpoons 3 C_{(g)}+2 D_{(g)}$, which is non-spontaneous at low temperatures, identify the correct option. [Assume $\Delta H^{\circ}$ and $\Delta S^{\circ}$ of reaction to be independent of temperature.]
A. It will be non-spontaneous even at higher temperatures.
B. If at equilibrium temperature increases, concentration of ' $C$ ' and ' $D$ ' will also increase at new equilibrium.
C. If volume of the container is suddenly increased at equilibrium without changing temperature then concentration of ' $C$ ' and ' $D$ ' also increase at new equilibrium.
D. If inert gas is added at constant volumes at same temperature the total pressure will increase.
