Answer:
A) the commercial links it established between Europe and the Far East along the Silk Road.
Explanation:
The Mongol expansion helped to reestablish the silk route, which made it easier for a Venetian explorer named Marco Polo to have access to the silk route and be the first European to cross that path and open this market between China and Europe. This allowed many trade agreements to be established and many products between the two continents to be sold. In this way we can see that the Mongol invasions on the Asian continent between 1215 and 1360 strengthened the commercial links that it established between Europe and the Far East along the Silk Road.
