Answer: B) Europeans created joint stock companies to engage in overseas trade.
One of the major changes in transregional trade patterns from 1500 to 1700 was the emergence of European joint stock companies, such as the Dutch East India Company (VOC) and the British East India Company. These companies were established to engage in overseas trade, particularly in Asia and the Americas. They played a significant role in facilitating and dominating long-distance trade during this period, establishing a global trade network that connected Europe, Asia, and the Americas. This development marked a shift in the dynamics of transregional trade as European powers sought to expand their influence and control over global trade routes.
