The attribution of early-nineteenth-century English fiction is notoriously problematic.
Fewer than half of new novels published in Britain between 1800 and 1829 had the
author’s true name printed on the title page. Most of these titles have subsequently
been attributed, either through the author’s own acknowledgment of a previously
anonymous or pseudonymous work, or through bibliographical research. One important
tool available to researchers is the list of earlier works “by the author” often found
on title pages. But such lists are as likely to create new confusion as they are to solve
old problems. Title pages were generally prepared last in the publication process, often
without full authorial assent, and in the last-minute rush to press, mistakes were frequently
made.
The passage suggests that which of the following factors contributes to the
“notoriously problematic” (line 1) nature of authorial attribution in earlynineteenth-
century English fiction?
A The unwillingness of any writers to acknowledge their authorship of
works that were originally published anonymously or pseudonymously
B The possibility that the title page of a work may attribute works written by
other authors to the author of that work
C The possibility that the author’s name printed on a title page is fictitious

答案给的是 B和C
但是我有点不认同B   最后一句话说的mistake 也不一定要是张冠李戴啊，还可能是把作者的名字打错了。
然而这个选项用了May这个词，又让我很想选它为正确答案。
求助大神，你们遇到这样的题是怎么思考的？

文章说了两个问题：1、大部分title用了假名，对应C。2、可通过list查询作者以前的作品，但是打印可能会出错，对应B，可能打印了其他作者的作品
