As a result of the Black Death (Bubonic Plague), the decline of the feudal system was accelerated.

Option C

Explanation:

During the middle of fourteenth century, the greatest pandemic of all times broke out and made it impossible for the authorities to control it. Due to the fear of getting contracted with the prevalent diseases, the officials of the feudal government chose not to go out and help the people suffering from plague. No help or assistance from the nobles made people lose faith in the feudal system and and eventually resulted in its decline.
