The correct answer is: c) Paik system.
The Paik system was a unique system of administration and governance used by the Ahoms, a Tai people who ruled over Assam from the 13th to the 19th centuries. Under the Paik system, all able-bodied men were required to serve in the army for a period of three years. After their service, they were given land and a house in return for their loyalty. The Paik system was a very effective way of maintaining order and security in Assam, and it helped to ensure the Ahoms’ long-term rule.
The Mansabdari system was a system of military and civil administration used by the Mughal Empire. It was based on a hierarchy of ranks, with each rank having a corresponding number of soldiers and/or officials. The Zamindari system was a system of land tenure in India under which a large landowner, known as a zamindar, held land from the government in return for a fixed rent. The Village council system was a system of local government in India in which villages were governed by a council of elders.
The Paik system was different from these other systems in that it was based on a system of conscription, rather than on a system of land tenure or local government. It was also different in that it was a very effective way of maintaining order and security in Assam.
