Final Answer :
C
Explanation :
NREM,stage III,is the deepest sleep.In this stage,the delta waves are highest in amplitude,slowest in frequency,and highly synchronized.The body,mind,and muscles are very relaxed.It is difficult to awaken someone in stage III sleep; if awakened,the person may appear confused and react slowly.During this stage,the body releases human growth hormone,which is essential for repair and renewal of brain and other cells.
