Answer:
Option: b) Farm laborers acquired more power to negotiate labor terms, forcing rural lords to adjust labor practices to avoid shortages of labor and food.
Step-by-step explanation:
The Black Death (the plague), was an epidemic that spread throughout Europe and Asia in the mid- the 1300s. The plague lasted for three years, and it killed one-third of all the people in Europe.
The requirement for farmers to work the land was high that it warned the manor lords. Serfs no longer tied to one master, they tend to leave and work for another lord. The manor lords had to make adjustments to make the condition more helpful for the peasants and keep them on their land. Wages were growing higher and the standard of living raised. The peasants became empowered and rebelled when the aristocracy tried to hold the changes carried about by the plague.
