Answer: B
Explanation:
The Black Plague or Black Death was spread from Asia to Europe through trading barges or ships. Since a lot of people in Asia contracted the plague, it was natural the rats on the ship also carried the disease. Where the ships landed, rats or their fleas hiding on humans would come with the travelers. While European countries were fighting wars during the plague, it mostly halted because of the sharply increasing deaths from the disease. Religion was used more for trying to cure the Black Death, and ironically there was more food and land for the survivors since there were less mouths to feed.
