Eysenck proposed that extraverts have a lower baseline level of arousal than introverts. This means that they are more likely to feel bored or under-stimulated in situations where they are not getting enough external stimulation. This is related to activity in the reticular activating system, which is responsible for regulating levels of arousal and attention in the brain. Therefore, option B, which suggests that extraverts are chronically under-aroused, is the best choice.
