Final Answer :
C
Explanation :
The stage of sleep described where the EEG becomes very active after an hour or so of sleep is the stage of rapid eye movement (REM) sleep. During this stage, the eyes move rapidly beneath the lids and most dreaming occurs. Nonrapid eye movement (NREM) sleep consists of stages 1-4, where the brain activity gradually decreases and dreams are less common. Spindles are brief bursts of rapid brain activity that occur during NREM sleep. "Slumber" is a general term for sleep and does not specifically refer to any stage of sleep.
