I am helping someone study for a CLEP test using a book of practice problems with answers. I'm struggling to understand the answer given for this problem:

Which is NOT true for entropy in a closed system according to the equation Δ S=Q/T?

A. Entropy is a measure of energy dispersal in the system

B. Equation is only valid for a reversible process

C. Changes due to heat transfer are greater at low temperatures

D. Disorder of a system decreases as heat is transferred out of the system

E. Increases as temperature decreases

They give the answer as C, with this explanation:

The equation relates to the change in entropy ( Δ S) at different temperatures. Entropy increases at higher temperatures (i.e. increased kinetic energy).

To me, it seems like C and E say the same thing, and that both are true, hence neither would be the correct answer. A, B, and D also seem to be true, so there would be no correct answer given among the choices. Am I missing something?
