Option b is the correct answer. Balaji Viswanath streamlined the Maratha administration after Shambhaji. As Sambhaji (1680-89) was succeeded by Rajaram, Shivaji II, Tarabai and Shahu. Balaji Vishwanath was the 6th Peshwa and the first in a series of hereditary Peshwas of the Maratha Empire. For his exemplary service to Chhatrapati Shahu in consolidating the empire and setting right many things in the kingdom, he is called the 'Second founder of the Maratha State'.
