Who is the author of Akbar Nama?

The correct option is Abu’l Fazl.

Akbar Nama (which translates to the "Book of Akbar") is the official chronicle of the reign of Akbar, the third Mughal Emperor, who ruled from 1556 to 1605. The book was written in Persian, which was the literary and court language of the Mughal Empire.

The author of this monumental historical work was Abu'l-Fazl ibn Mubarak, who was one of the "Nine Jewels" (Navaratnas) in the court of Emperor Akbar. Akbar commissioned Abu'l-Fazl to write a detailed history of his reign, which took several years to complete, starting around 1589. The work provides a detailed account of Akbar's life, the administration of his empire, his ancestry, and the socio-cultural conditions of India during that era. It is divided into three volumes, with the third volume being the famous Ain-i-Akbari (Administration of Akbar).
