Final Answer :
C
Explanation :
The sleep-wake cycle follows a circadian rhythm, which refers to a 24-hour cycle of physiological and behavioral processes, such as the sleep-wake cycle, hormone production, and body temperature variations. Infradian rhythms occur less frequently than once a day (e.g. menstrual cycle); diurnal rhythms refer specifically to animals that are active during the daytime and sleep at night; ultradian rhythms occur more frequently than once a day (e.g. REM sleep and stages of sleep within a night's sleep).
