Answer:
The best answer to the question: Which character says these words: "Who is this general whom I have heard so much about, who is at once both fierce and gentle, wise and playful, mighty and humble?", would be, C: Saint George.
Step-by-step explanation:
Saint George was a Christian soldier who became almost the topic of legends and myths, especially in England, after the return of the Crusaders. There are many stories that surround this Catholic saint, who for a time became the patron of England, but whose iddentity began to be lost with the rise of the Church of England and the reduction of Catholicism in the country. He was part of the Praetorian army of Diocletian and was persecuted and executed by this emperor because he refused to forego his Christian faith.
