Final Answer :
C
Explanation :
Peter's brain wave pattern consisting of low-frequency delta waves indicates that he is in stage 3 or 4 of non-REM (NREM) sleep. These stages are characterized by deep, restorative sleep with slow brain activity and relaxation of the body's muscles. Stage 1 is the transition stage between wakefulness and sleep, while stage 2 is a deeper stage of NREM sleep with brief periods of brain activity known as sleep spindles and K-complexes. REM sleep is characterized by rapid eye movements, vivid dreams, and a more active brain wave pattern similar to wakefulness.
