The correct answer is B. Interpret and analyze primary or other secondary sources

Explanation:

Regarding sources, there are mainly primary and secondary sources. In the case of primary sources, these sources are documents, recordings, photos and others that are a first-hand account of events, this implies the authors of these sources experience or witnessed the events they are referring to. On the other hand, secondary sources are not first-hand accounts, but an analysis, summary, interpretation or collection of primary or secondary sources, which imply the author did not experience the events but writes using sources. Thus, secondary sources interpret and analyze primary or other secondary sources.
