Redaction is the process of hiding or obscuring part of an electronic document or image from view, typically to protect sensitive or confidential information. It is not related to database transactions, highlighting content, or movie directions.
Correct answer: A way of hiding part of an electronic image or document from view. Redaction is the process of permanently obscuring or removing sensitive/confidential portions of a document or image (e.g., blacking out SSNs or classified text) before release. It has nothing to do with transaction rollback (a database concept), highlighting content (the opposite of hiding it), or film production terminology — those are all plausible-sounding but unrelated distractors.
