A secondary source is written or made by someone who didnt experience the event, and C is the only option where there is something written by someone who didnt experience the event.
B. A historian who wrote a book about politics in Jamestown during it's founding period.
Explanation:
A secondary source is a source that was NOT written by someone who was at the original scene. All the other answers include someone who might have been at the original Jamestown. A historian writing about Jamestown, however, was using primary surces, but was not actually at Jamestown. Hope this helps & feel free to ask for any clarification!
