C. The Christian church
Step-by-step explanation:
The black death is also referred to as black plague, great mortality, or pestilence. It was a bubonic plague pandemic that occured between 1346 and 1356 in Afro-Eurasia. Also, it lead to the death of between 75,000,000 - 200,000,000 people in North Africa, Europe and Eurasia, making the plague the most fatal pandemic to be recorded in human history.
Furthermore, a bacteria known as Yersinia pestis was responsible for this fatal, epidemic disease and it was transmitted from an infected person or rodent to humans when bitten by infected fleas. Some of the symptoms of the black death are fever, aching joints, chills, diarrhea, delirium, nausea and vomiting, formation of buboes, headache, etc.
According to the Roman Catholic (Christian) church, the plague was as a result of the sins of the people that is being punished by God. Thus, a great number of the terrified population turned to the church in order to be forgiven for their supposed sins, thus making the church become more powerful and wealthier.
In conclusion, due to people asking The Christian church questions about the cause of the black death, their authority was eventually ceased.
