The correct option is C Sabha
The Chola kingdom had four assemblies to carry its business: Nadu decided all the cases within the district and the Nattars were its members. Nagaram was responsible for trade and commerce and took steps to promote trade. The members of this assembly were called the Nagarttars. Ur solved problems at the village level, and finally, Sabha specifically dealt with solving problems of the Brahmins. Thus, in this scenario, Rakesh and Murali would have to appeal to the Sabha.
