The correct answer to this question would be alternative D)"None of the above."
State governments fund public libraries, but the library board of directors determine which books to include.
Once a library has legal authorization to function and has funding from the government, it's usually managed by a board of directors or a library council, and it appoints a librarian to be library director or library manager. Then, it builds its collection of books and media, which is decided by the board or council managing the library.
