That can be taken many different ways maybe: they push themselves to hard and don’t know when to take a break or they cant settle down, sleep or, don’t know when to stop.
I believer your answer is false because what's the point in a privacy law if you can't have privacy. If that makes sense haha :)

Some reminders are necessary:
Artery does not have valves, the blood pressure on it is very high, there is no risk of blood backflow, so it does not need valves
Arteries are vessels that transport blood from the heart to capillaries.
Veins are vessels that transport blood back to the heart from capillaries.
According to these reminders, you could conclude that:
A is false (no backflow in arteries)
C is false (no backflow in arteries)
D is false ( veins take blood to the heart)
so the right answer is B
