Answer 1

REM rebound experienced by mammals after REM sleep deprivation suggests that dreaming during REM sleep is a biologically necessary function for emotional processing and brain health. Therefore correct option is D

Step-by-step explanation:

The best indication that dreaming serves a necessary biological function is provided by the fact that most mammals experience REM rebound. When mammals, including humans, are deprived of REM sleep, and then allowed to sleep without disturbance, they exhibit REM rebound by spending more time in REM sleep than usual. This phenomenon suggests that REM sleep, which is closely associated with dreaming, is homeostatically regulated and maybe crucial for emotional processing and regulation, learning, memory, and overall brain health.
