Answer:
Option D is false
Option E is false since it is incomplete
Option C is false
Explanation:
Well, regarding option D it is considered false because the functional groups would be:
Acetone (which is not used as an energy source, is exhaled or excreted as waste), Betahydroxybutyrate and acetoacetate (if not oxidized to be used as an energy source).
In statement C it is false, because the formation of ketone bodies increases with the presence of acetylcoA, but acetone is one of those that will always be witnessed in a lower percentage, since it is excreted by the body as waste, both either by the airways in the exhalation (characteristic ketone breath) and in the urine (cetouria)
