What is considered a secondary source in research?

A secondary source in research is defined as a document or recording that discusses, analyzes, or interprets primary sources. This means that it does not present original data or firsthand evidence but rather relies on primary sources to provide analysis or commentary. For instance, a historian writing an article about a specific event would use primary sources, such as diaries or photographs from that time, and then create a scholarly analysis based on those sources.

Secondary sources are essential for providing context, interpretations, and critical discussions of original materials, helping researchers understand the significance and implications of primary data. This makes option B the accurate choice regarding what constitutes a secondary source in research.
