'Raichur' Doab is the land situated between which two rivers?

Tungabhadra and Krishna

The correct answer is Option (1) → Tungabhadra and Krishna

The Raichur Doab is the land region located between the Tungabhadra and Krishna rivers in South India.

The name "Vijayanagara," meaning the "city of victory," applied to both a city and an empire. This empire, established in the fourteenth century, once extended from the northern banks of the river Krishna to the southernmost part of the Indian peninsula. However, in 1565, the city was ransacked and subsequently abandoned.

Krishnadeva Raya’s rule was characterised by expansion and consolidation. This was the time when the land between the Tungabhadra and Krishna rivers (the Raichur doab) was acquired (1512), the rulers of Orissa were subdued (1514) and severe defeats were inflicted on the Sultan of Bijapur (1520). Although the kingdom remained in a constant state of military preparedness, it flourished under conditions of unparalleled peace and prosperity. Krishnadeva Raya is credited with building some fine temples and adding impressive gopurams to many important south Indian temples. He also founded a suburban township near Vijayanagara called Nagalapuram after his mother. Some of the most detailed descriptions of Vijayanagara come from his time or just after.
