Final answer:
Drive theory indicates that deviations from homeostasis lead to physiological needs, creating psychological drive states that motivate behavior to fulfill those needs and reestablish homeostasis.
Step-by-step explanation:
Drive theory states that deviations from homeostasis create physiological needs that result in psychological drive states that direct behavior to meet the need and ultimately bring the system back to homeostasis. For instance, when you haven't eaten for some time, your blood sugar levels drop, which induces a physiological need for food. The resulting psychological drive state, which is hunger, motivates you to seek and eat food, thereby restoring your blood sugar levels to normal.
Furthermore, drive theory suggests that once a behavior successfully reduces a drive, such as eating when hungry, it becomes a habit. This habit is likely to be repeated in future situations where that same physiological need arises. Therefore, the correct answer to the question is B) homeostasis.
