Answer:
B) historian
Step-by-step explanation:
Thucydides unlike his predecessor Herodotus did not hyperbolize his stories but wrote about them as factually as he could. He wanted to record history as it happened and to write it in such a way that future generations would be able to learn from his work. He is famous for his writings about the Peloponnesian War and the struggles of Athens and Sparta in that war.
