b.

c.

d.
a documentary about the american revolution

The correct answer is D. A documentary about the American Revolution is not an example of a primary source.

Explanation:

A primary source refers to the documentary sources that are considered material from some source of the moment, in relation to a phenomenon or event that may have an interest in being investigated or reported, that is, it is the raw material that is used to make a certain work.

In the case of historiography, it is what has been used to write history. As the documentary is a collection of data, and not the event itself, it cannot be considered a primary source.
