The question asks us to identify the incorrect pair. Let`s evaluate each option:
Option 1: Abul Fazal being the Chief Advisor is a valid pair.
Option 2: Faizi being a poet is also correct.
Option 3: The statement that Birbal is the Finance Minister is incorrect. Birbal was not a Finance Minister, but rather a court jester or advisory to Emperor Akbar.
Option 4: This option states that all pairs are correct, which is not true because option 3 is incorrect.
Therefore, the correct answer is option 3. The pair of Birbal being the Finance Minister is incorrect. It is important to note that Birbal was not a Finance Minister, but a court jester in the court of Emperor Akbar.
