The most accurate response to the effect of the fall of the Byzantine Empire to the Ottoman Turks on global trade is:
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.
This reflects the reality that the fall of the Byzantine Empire in 1453 led European nations to seek alternative trade routes to Asia, ultimately contributing to the Age of Exploration and the expansion of maritime trade.
