D is correct.
E may imply that the hormone itself is asleep or awake.
but why cannot D mean that it is secreted during the hormone's sleep rather than its waking hours? I mean, is there rule that explain the difference between using D and E?
Both "asleep" and "awake" are adjectives, so they have to modify a noun and the only noun is the hormone. This means that the hormones sleep which is illogical.
On the other hand, "sleep" and "waking hours" are nouns and stand on their own. In this sentence the hormones are not doing the sleeping.

Hey All,
Lots of good discussion here, and I think the right answer was explained here and there in pieces. I thought I'd take a stab at putting it all together in one place.
The human growth hormone, made by the pituitary gland, is secreted during sleep in higher concentrations than when awake.
(A) during sleep in higher concentrations than when awake PROBLEM: "When" is a relative pronoun, meaning it's a modifier, meaning it has to modify something. Relative pronouns always modify nouns, but there is no adequate noun. Who is "awake" in the phrase, "when awake" (something has to be).
(B) when sleeping in higher concentrations than waking hours PROBLEM: Again, who's sleeping?
(C) in higher concentrations during sleeping than waking PROBLEM: This sounds like the comparison is between time spent asleep and time spent WAKING UP. The comparison should be between being asleep and being awake.
(D) in higher concentrations during sleep than during waking hours ANSWER: Gets rid of "When" and compares the right two things.
(E) in higher concentrations when asleep than when awake PROBLEM: Two "Whens" = double the trouble.
