According to Kautilya's Arthashastra, the territorial divisions were organized hierarchically. The approximate sizes associated with these terms are: - Samgrahana: Centre for 10 villages - Karvatika: Centre for 200 villages - Dronamukha: Centre for 400 villages - Sthaniya: Centre for 800 villages Thus, the ascending order by size is Samgrahana, Karvatika, Dronamukha, Sthaniya. However, the options provided do not match this order. Option C lists the units as Sthaniya, Dronamukha, Karvatika, Samgrahana, which is the descending order of size. It appears there is a discrepancy between the question asking for ascending order and the options provided, with option C representing the descending sequence. Assuming option C is the intended correct answer despite the question asking for ascending order.
