• A. Explanatory note
• B. Index
• C. Video-recording
• D. Reserved materials

Answer: (A)

An annotation is a concise, informative note attached to a work that explains its content, scope, and usefulness for a reader. This matches the idea of an explanatory note, since the purpose of an annotation is to describe what the work covers and why it might be helpful for a particular research question. An annotation may summarize the main ideas, note the author’s perspective or credibility, and indicate how the work relates to other sources, helping a researcher quickly assess its relevance and value. An index is a separate list of topics with page references used to locate information inside a text, not a note about the work itself. A video-recording is a form of media, not a descriptive note. Reserved materials refer to items with restricted access or special handling, not descriptive notes about content.
