B. ignore all proofreader marks in that line of text
The word "stet" next to a line of text being proofread means that all the proofreader marks in that line of text should be ignored. It means to let it stand, meaning don't change it. For example, the proofreader crossed out a word for deletion thinking that it was irrelevant only to realize later that it is actually important for identifying a specific type. The proofreader would then write stet in a circle next to that line so that the now relevant word is not deleted.
Answer:
The answer to the question: If you see the word "stet" in a circle in a margin next to a line, what would you expect the proofreader means, is: B: Ignore all proofreader marks in that line of text.
Explanation:
The reason comes from learning a bit about proofreading and editing marks that are used by these people to point what, and where, something inside a text needs to be changed by a writer. In essence, "stet" is an obelism, a form of the Latin verb statum, or sto, that in proofreading, indicates that the text delimited by dashes, or dots, and who is followed by the mark "stet" circled on top, or beside it, does not need to be changed by the writer. However, this lack of need to edit will only apply to the text underlined, and followed by "stet", and not others.
