Concept:"Censor" means to officially examine and remove parts of a publication, film, or news that are considered offensive, harmful, or unsuitable for the public.
Explanation:The correct word must fit the idea of withholding or removing sensitive material before it is released to the public.
"Edited" means improved or corrected a written work; it does not necessarily mean removing objectionable parts.
"Examined" only means inspected carefully.
"Isolated" means set apart or separated, which does not fit the context.
Therefore, the word that best completes the sentence is "censored" because it carries the exact meaning of suppressing or cutting out objectionable content officially.
Answer:B. censored
