Right answer and explanation
Right answer: B. Because the body clock is at its lowest in the morning, so sleepiness sets in
The body clock has a pronounced trough in alertness at night and in the early morning hours. After a night shift this comes on top of having been awake a long time, and the combination carries a high risk of microsleep. Plan the trip home — public transport, sleep before driving, or have someone collect you.
