As the night progresses, there is typically less of the deeper stages of non-REM sleep (stages 3 and 4) and more of the lighter stage of non-REM sleep (stage 2) and REM sleep. This pattern is known as the sleep cycle and is repeated throughout the night. Therefore, choice A, which states that there will be less of stages 3 and 4 and more of REM sleep, is the best choice.
