Option 1: (C), (D), (B), (A) -> Places Akbar before Humayun's recovery, which is incorrect.
Option 2: (D), (C), (A), (B) -> Humayun regained territories (1555), followed by Akbar's reign (1556-1605), Jahangir's reign (1605-1627), and finally the Diwani of Bengal (1765).
Option 3: (D), (C), (B), (A) -> Incorrectly places the Diwani of Bengal (1765) before Jahangir's reign (1605-1627).
