Final answer:
The reactive drive in the four-drive theory is the drive to react, while the other drives are proactive.
Step-by-step explanation:
In the context of the four-drive theory, the drive to react is the reactive drive, as the name suggests. This drive refers to the instinctual, automatic response to a stimulus or situation. For example, if a person suddenly hears a loud noise, their drive to react would urge them to jump or cover their ears.
In contrast, the other drives in the theory are proactive. The drive to acquire refers to the motivation to obtain resources and rewards, the drive to defend pertains to protecting oneself and one's possessions, the drive to bond involves forming connections and relationships, and the drive to comprehend is the desire to understand and make sense of the world.
Overall, the reactive drive in the four-drive theory is the drive to react, while the other drives are proactive in nature.
