A very strong centralized political authority and a very weak provincial or local political authority: This statement is incorrect. The feudal system is characterized by decentralized political authority. It involves a system where local lords or landowners have significant power and control over their territories. There is a lack of a strong centralized authority.

Emergence of administrative structure based on control and possession of land: This statement is correct. In the feudal system, power and authority were closely tied to the ownership and control of land. Land was the primary source of wealth and influence, and those who owned land had political and economic authority.

A lord (landowner) would grant land to a vassal (subordinate), and in return, the vassal would provide military service and other forms of loyalty and support to the lord
