D. Not asleep is the correct answer.

Answer 2

If you detect a predominance of beta waves in a subjec undergoing a sleep experiment, the subject is most likely in a transition between waking and sleeping. This is because most people exhibit the beta waves when they are awake. Beta waves are associated with wakefulness. The waves have the highest frequency and the lowest amplitude and they are very inconsistent in pattern.
