Orexin is a neuropeptide that plays a role in regulating feeding behavior and appetite. Its main function is to promote wakefulness and arousal, but it also stimulates hunger and food-seeking behavior. Orexin is thought to be most active in animals when they are approaching starvation, indicating that its primary role is to ensure survival by motivating animals to seek food when necessary. Therefore, option B is the best choice.
