Final Answer :
C
Explanation :
The low-amplitude, irregular brain wave patterns and the description of Bailey's eyes darting back and forth beneath her closed eyelids are indicative of REM (rapid eye movement) sleep, which typically occurs about 90 minutes after falling asleep. Therefore, the researcher can conclude that Bailey has just entered REM sleep.
