I would say the answer is C but I’m not totally sure sorry
One, Because it is written in old English. Secondly, Shakespeare invented many words which he used in his plays and the exact definitions are not known. The majority of the terms used are from hundreds upon hundreds of years ago and the 21st CE uses modern English. I don't think Shakespeare would know what "Lit" and "Fleek" would mean if he were to come back.
The correct answer is HE THINKS FATHER WILLIAM IS TOO OLD TO BE DOING WHAT HE DOES.
