I think the correct answer is C. The chemical reaction NaCl + LiNO3 ---> NaNO3 + LiCl do not represent an oxidation-reduction reaction. An oxidation-reduction reaction involves the gaining and losing of electrons of the elements involved in a reaction where it is essential that as one is losing some electrons, the other is gaining the electrons lost.
