The correct sequence of sleep stages during the first 90 minutes of sleep is stage 1 NREM, stage 2 NREM, stage 3 NREM, stage 4 NREM, and finally REM sleep. This sequence is typically repeated several times throughout the night, with each cycle lasting approximately 90 minutes. Choice B is incorrect because REM sleep occurs after NREM sleep stages, and stage 4 NREM sleep is typically reached later in the night. Choice C is incorrect because there is no stage 1 REM, and stage 4 is typically the deepest stage of NREM sleep. Choice D is incorrect because it does not accurately describe the stages of sleep.
