The Russain princes role was that : "They acted as administrators and collected tribute on behalf of the Mongols." Hence, Option A is correct .
The Mongol Empire employed a system of indirect rule over conquered territories. They allowed local rulers to maintain their positions, as long as they acknowledged Mongol supremacy and fulfilled their obligations.
In the case of Russia, the princes played a crucial role in this system. They collected tribute from the Russian people, recruited troops, and ensured internal order.
This arrangement benefited both parties.
The Mongols gained control over a vast territory without having to directly administer it, while the princes retained some level of power and authority within their own domains.
