The correct answer is C. Global trade expanded to include all water routes as European countries began to search for new ways to reach Asia by bypassing the route through the Ottoman Empire.
After the fall of the Byzantine Empire and the subsequent rise of the Ottoman Empire, European nations sought new trade routes to access Asia, particularly for spices and luxury goods. This led to significant exploration and the eventual emphasis on maritime trade routes, culminating in expeditions by explorers like Columbus and Vasco da Gama. As a result, trade expanded to include various sea routes, effectively transforming global trade dynamics.
