Ans. Option B is correct.
As the volume increases the pressure decreases, the equilibrium shifts towards the more no. Of moles means towards the reactants.
As the temp. decrease , the equilibrium favours the reaction by increasing the temperature in exothermic reaction.
So if the temp increases, the equilibrium shifts towards the reactants.
