Answer:
D) A secondary source.
Step-by-step explanation:
A secondary source is any source of getting information or without the author participating in the scenes described in the text. The author may or may not be taking or writing based on his research in writing the book which can be a result of interpreting, evaluating, and analyzation of the scene described. Secondary sources can be academic/ scholarly books, articles, and commentaries, etc.
George Rawlinson's "How the Hyksos were expelled from Egypt" is a secondary source for it describes a scene that is from the past but which he is not a participant of. He is just interpreting, analyzing, and evaluating the event and then writing about it.
Thus, the correct answer is option D.
