Ashtapradhan (Council of Eight) was the administrative council of Shivaji's Maratha Empire, formalized in 1674. The eight ministers were: Peshwa (Prime Minister), Amatya (Finance Minister), Sachiv (Secretary), Mantri (Interior Minister), Senapati (Commander-in-Chief), Sumant (Foreign Minister), Nyayadhish (Chief Justice), and Pandit Rao (Royal Priest/Household Management). Harihara I (option A) founded the Vijayanagara Empire. Krishnadevaraya (option B) was its greatest ruler with a different administrative structure. Balaji Baji Rao (option D) was a later Peshwa, not associated with Ashtapradhan.
