Answer: (A)

Verified step by step guidance

1. Understand the different stages of sleep: NREM Stage 1 (light sleep), NREM Stage 2, NREM Stage 3 (deep sleep), and REM sleep.
2. Recall that sleepwalking typically occurs during deep sleep, which is characterized by slow-wave activity and is restorative in nature.
3. Identify that NREM Stage 3 is known as deep sleep or slow-wave sleep, where the brain exhibits delta waves and the body is in its most relaxed state.
4. Recognize that parasomnias such as sleepwalking are most commonly associated with NREM Stage 3 because the brain is partially aroused but the body remains inactive.
5. Conclude that sleepwalking is most likely to occur during NREM Stage 3 (deep sleep), rather than during lighter stages or REM sleep.
