Explanation: One of the important characteristics of the Vijayanagar administration was the amara- nayaka system.

• The top-grade officers of the army were known as Nayaks or Palaiyagars or Poligars.
• Interestingly, these officers were granted land (called amaram) in lieu of their services while soldiers were usually paid in cash.
• The nayaka was responsible for expanding agricultural activities in his amaram (area).
• He collected taxes in his area and with this income maintained his army, horses, elephants, and weapons of warfare that he had to supply to the raya or the Vijayanagar ruler.
• The nayaka was also the commander of the forts.
