Answer: B. must be awake and aware to breathe

Explanation:

Sleep can be considered as unusual in dolphins. In dolphins during sleep only one hemisphere of the brain closes and the opposite side of the eye also get closed. The other eye remains open, and the other brain part remain functioning. This process facilitates in breathing during sleep as breathing and sleep cannot be simultaneous. Also the brain controls the response to the external stimuli during sleep.
