Final answer:
The Mongol Empire helped stabilize trading networks between China and the Mediterranean world through infrastructure improvements, security guarantees, and fostering economic expansion. The correct option is (B).
Step-by-step explanation:
The Mongol Empire helped stabilize trading networks between China and the Mediterranean world through several means.
First, the Mongols improved the physical infrastructure of trade routes, such as the Silk Road, making travel safer and quicker. They built relay stations called caravanserai that provided rest, supplies, and trade opportunities for travelers.
Second, the Mongol Empire guaranteed the security of travelers, reducing the risk of banditry and piracy along the trade routes.
Finally, the Mongols fostered economic expansion by reducing taxes and facilitating trade. Their rule created a period of peace known as the Pax Mongolica, which allowed for increased exchanges of goods, ideas, and technologies between China and the Mediterranean world.
