Quizplus · Accepted Answer

Slow-wave sleep, also known as stage 3 and 4 sleep, gradually declines in percentage as we age. In early adulthood, it makes up around 20% of total sleep time, while in older adulthood it may be less than 10%. Stages 1 and 2 sleep also decrease slightly with age, but not as significantly as slow-wave sleep. REM sleep remains relatively stable throughout adulthood. Therefore, the correct answer is C) slow-wave sleep.
