C. A chart that identifies the number of new homes built each year
D. A magazine article that reviews the latest books and movies

 The correct answer is:  [C]:

 " A chart that identifies the number of new homes built each year. "

Explanation:

Note:  This is the only answer choice given that is an example of a "graphical source".  A chart that identifies or represents data can be demonstrated using a graph.

Consider the other answer choices:

[A]:  A non-fiction book about the economical consequences of a war;

       as a source, would tend to be an "objective source"—yet not a"graphical source".

[B]:  A book of poetry—as a source—is not a source that provides statistical data/information that is "graphed".

[C]: As mention for choice [C]:  A magazine article providing reviews is not statistical data/information that is "graphed" .

a, b, and c are all correct.
