The correct answer is C) Eusebius.
Eusebius created a system for classifying the New Testament books.
We are talking about Eusebius of Caesarea (260-349). He was the first interested in compiling all kinds of texts and information to create a historical document of Christianity. That is why modern theologists consider him "the Father of the Church. It was a great deed because before his work, there was no order of books or chronological selection of documents or events.
