The answer is C- Having a peer in the car.
Reason: Peer pressure.
I don't think it's not possible to never know when you're hungry, however it may be hard to tell when you are hungry. To tell if you are genuinely hungry, you can check if you are angry, if your stomach is growling or if you wouldn't mind eating anything. You could also drink some water; if you can feel it in your stomach you need to eat.
Hope it helps, good luck! :)
