B. The Mongols made the routes safer for merchants to travel, resulting in increased trade.

Explanation:

A trade route can be defined as a logistics network that comprises of long-distance pathways and stoppages used by merchants for the commercial transportation of goods. Trade routes can either be established on land with caravans being used for transportation of goods or on sea with merchant ships or vessels being used by traders.

In ancient times, the Mongol empire is one which was typically known for linking Asia and Europe during the era of frequent trade between the east and the west. The Mongols encouraged trading with foreigners and as such increased the level of trades by being hospitable, tolerant and providing security for the foreign traders along the silk road.

Hence, the statement which best described the change in long-distance trade routes between China and the Mediterranean world in the 1200s and early-1300s is that, the Mongols made the routes safer for merchants to travel, resulting in increased trade.
