Which statement best describes primary sources in credibility assessment?

• A. Primary sources are always the most reliable for any topic.
• B. A credible primary source is defined by original data or official records.
• C. Primary sources should be avoided.
• D. Primary sources require corroboration in all cases.

Answer: (B)

Primary sources provide direct evidence from the time or event, such as original data or official records. In credibility assessment, what makes a primary source credible is that it is original data or an official record—this authenticity and proximity to the topic give it strong evidentiary value. However, credibility isn’t guaranteed by being primary alone; it also depends on who produced it, when and how it was collected, and potential biases or gaps in the information. The other statements mislead: primary sources aren’t automatically the most reliable in every situation, they shouldn’t be categorically avoided, and while corroboration is good practice, there are cases where a single credible primary source can stand on its own or be the best available evidence.
