Inadequate sleep can result in all of the following except a. poor health b. difficulty concentrating. c. decreased reaction time. d. diminished coordination

Diminished coordination would seem the answer that won’t fit the category

If you don't sleep very often, then you could start to see a decrease in health. If you don't sleep, you may have difficulty concentrating because you're tired. If you don't sleep, your reaction time would be a little off due to thinking about the dreams you coulda had but no, you decided to watch the new episode of The Walking Dead (haha). I don't really see how lack of sleep would alter your coordination so I would choose D. If I get it wrong, I apologize. I tried my best.  Hope this helped :)
