Who among the following is regarded as the forerunner of the revenue administration in medieval India?

Sher Shah Suri (1540-1545) established a highly efficient revenue administration system that became the foundation for Akbar's later reforms. He introduced land surveys, standardized measurement units, and classified land into three categories for taxation. His system was so well-organized that Akbar largely adopted it. This makes Sher Shah the true forerunner of medieval Indian revenue administration.
