Quizplus · Accepted Answer

The research on hypothalamic lesions in rats demonstrated that lesions to the lateral hypothalamus resulted in decreased food intake and body weight, while lesions to the ventromedial hypothalamus resulted in increased food intake and body weight. This suggests that the hypothalamus plays a vital role in regulating body weight and keeping it in homeostasis. Therefore, choice C is the best conclusion that the research supports.
