Bernier's main argument concerning Mughal administration is best described by: C. The Mughal government's practice of tax farming was not an effective means of promoting economic growth.
Bernier's primary argument on Mughal administration, as a keen observer during the era, centered on the inefficiency of the government's tax farming system. He contended that relying on tax farming, where private entities collected taxes, was ineffective for promoting economic growth within the Mughal Empire.
This critique suggests that the Mughal administration's reliance on such a practice hindered rather than facilitated economic development. Bernier's observations, reflecting his encounters with Mughal governance, contribute insights into the challenges and shortcomings faced by the empire during that period, particularly in the realm of economic management.
Option C is the correct answer.
