Muscle tone is slightly lower from wakefulness during which sleep stage?

Muscle tone drops as you fall asleep, but the amount of reduction depends on the stage. In non-REM sleep, the tone is lower than wakefulness, yet not dramatically reduced—your body remains relatively capable of movement. REM sleep, by contrast, involves near-complete muscle atonia to prevent dream acting. Since the question describes a slight decrease from wakefulness, non-REM sleep fits best as the stage where tone is modestly lower than when awake, with Stage 2 illustrating this milder reduction. So, the best answer is non-REM sleep.
