The correct answer is C. It summarizes and evaluates the source used.
Step-by-step explanation:
The purpose of an annotated bibliography is to list all the sources that were used in a paper as well as briefly describe the content of the source and evaluate this. These features can be seen in the annotation presented because the author first lists the source through details such as author, date of publication, publisher, etc. Then there is a brief summary of the content of the source, this can be seen in "gives a comprehensive history of the United States justice system" or "highlights influential justices", which are general statements about key details. Finally, there is an evaluation of the source "this book makes an excellent, unbiased resource".
