Which factors contributed to the decline of feudalism?

Explanation

The weakening of feudalism was primarily caused by factory competition challenging traditional handicrafts and manorial production (II), as well as the growth of transportation, trade, and the discovery of new international markets (III). While the migration of serfs to towns (I) also played a role, the combination of II and III had a more direct impact. The rise of business corporations (IV) was less influential in this decline.
