To answer this question, you need to understand the Nayankara system of Vijayanagar.
The Nayankara system was a land revenue system implemented during the Vijayanagara Empire. Under this system, lands were assigned to individuals in exchange for annual tributes and military service.
Option A) Persons against annual tributes and military service - This option is correct because it accurately describes the assignment of lands under the Nayankara system. Individuals were granted lands in return for their commitment to pay annual tributes and provide military service to the empire.
Option B) Mathas for the maintenance of temples - This option is incorrect. While the Vijayanagara Empire did play a significant role in promoting and supporting Hindu temples, the Nayankara system primarily focused on assigning lands to individuals, not mathas.
Option C) Women without any source of income - This option is incorrect. The Nayankara system did not specifically assign lands to women without any source of income. The system was mainly concerned with military service and revenue collection.
Option D) Brahmins for charitable trusts - This option is incorrect. The Nayankara system did not assign lands to Brahmins for charitable trusts. Again, the focus of the system was on tribute payments and military service.
Therefore, the correct answer is option A) persons against annual tributes and military service.
