• B. The region between Godavari and Krish rivers
• C. The region between Tapi and rmada rivers
• D. The region between Krish and Tungabhadra rivers

Hint:

Doab = Land between two rivers ($Do$ = two + $Ab$ = water). - Raichur Doab is uniquely trapped between the Krish and Tungabhadra rivers, serving as the geopolitical battleground of the Deccan.

Answer 1

The Correct Option is D

Concept: In geographical terminology, a *Doab* refers to a highly fertile tract of alluvial land situated between two confluent rivers. Due to high agricultural yields and economic wealth, these zones often became points of military contention between rival kingdoms.

Step 1: Geographically defining the Raichur Doab.
The Raichur Doab is a triangular landmass located in the southern Deccan plateau. It is bounded turally by:
• The Krish River along its northern perimeter.
• The Tungabhadra River along its southern perimeter.

Step 2: Alyzing its historical context with the Vijayagara Empire.
Control over this highly lucrative, fertile region sparked a long-standing, multi-generatiol conflict between the Hindu rulers of the Vijayagara Empire and the Islamic rulers of the Bahmani Sultate (and its later successor states, like the Adil Shahi dysty of Bijapur). In 1512, the greatest morch of the Tuluva dysty of Vijayagara, Krishdeva Raya, launched a successful military campaign to capture the fortress of Raichur and assert complete domince over this doab.

Step 3: Selecting the correct choice.
Based on the geographical boundaries of the Raichur Doab, it lies between the Krish and Tungabhadra rivers. This corresponds to Option (D).
