The best source to analyze the Persian perspective of the Mongol Empire during the Mongol rule would be:
A. the Jami' al-tawankh
The Jami' al-tawankh, also known as "The Compendium of Chronicles," was written by the Persian historian Juvayni and provides insights into the Mongol Empire from a Persian viewpoint, documenting events, cultural exchanges, and the impact of Mongol rule in Persia. In contrast, the other options would either not provide a direct Persian perspective or pertain to different contexts altogether.
