I Assume that these are meant to be equilibria.
in which case, C is intended to be a shift to the left. However, you might point out to teacher that as entropy is negative (inc in the no moles of gas) then increasing temp would tend to oppose the positive value of the enthalpy change, so that the free energy (delta G) would become increasingly negative. Since no information is given on the temperature of this rxn, then it is not possible to say.
In D, there are 2 moles on the left an d one on the right, entropy is positive, the term -(TdeltaS) becomes more negative as temp increases, in this case, teh rxn is favorable at all temperatures. If it is at equilibrium, an inc in temp would certainly shift the balance in the endothermic direction, to the left.
