Based on the given excerpt above from Boccaccio's The Decameron, Boccaccio would most likely feel about the actions of the flagellants, who warned Christians to repent because he would find their actions appropriate because he believed human sin may have caused the plague. The answer would be option C. Hope this helps.
The correct answer is option C. "He would find their actions appropriate because he believed human sin may have caused the plague". In the passage of "The Decameron" by Boccaccio that is included in the question it is stated that the author believes that one of the causes of the plague could be God's punishment for our sins. In this scenario is likely that Boccaccio would feel that flagellants do a good thing in hurting themselves to seek for God's mercy.
