Which of the following is an example of a primary source?

A primary source provides firsthand information or original data, such as an interview, where the information comes directly from the source. Option A (journal article) is typically a secondary source, as it analyzes or interprets primary data. Option B (book) is usually secondary, unless it is an autobiography or original document. Option D (website) can contain primary or secondary information but is not inherently primary. Conducting an interview directly gathers original data, making it a primary source.
