Option 1: Sangam - This option is incorrect. The Sangam dynasty was not ruling in the Vijayanagar empire during the Battle of Talikota. The Sangam era refers to a period in ancient Tamil literature and is unrelated to the Vijayanagar empire.

Option 2: Aniridu - This option is incorrect. There is no historical evidence of an Aniridu dynasty ruling in the Vijayanagar empire. It is possible that this option is a typographical error.
