Modern Research on the Physiological Mechanisms Responsible for Hunger Have

Modern research on the physiological mechanisms responsible for hunger have revealed that:

A) as a function of hunger regulation, the lateral hypothalamus (LH) is the location of both the "hunger on" and "hunger off" centres.
B) as a function of hunger regulation, the ventromedial hypothalamus (VMH) is the location of both the "hunger on" and "hunger off" centres.
C) while involved in hunger regulation, the lateral hypothalamus (LH) and ventromedial hypothalamus (VMH) are not actually "hunger on" and "hunger off" centres.
D) as a function of hunger regulation, the lateral hypothalamus (LH) is the "hunger on" centre and the ventromedial hypothalamus (VMH) is the "hunger off" centre.
