Which of the following town was built by the ruler Vijayalaya in Kaveri delta?

Thanjavur

The correct answer is Option 4- Thanjavur

The town of Thanjavur was built by the ruler Vijayalaya in the Kaveri delta.

Vijayalaya was the founder of the Chola dynasty in the 9th century AD. He defeated the Muttaraiyar, who were ruling the Kaveri delta at that time, and built the town of Thanjavur as his capital. Thanjavur became a major center of Chola power and culture, and it is still an important city in Tamil Nadu today.

Tiruchirappalli, Tiruppur, and Madurai are all other important cities in Tamil Nadu, but they were not built by Vijayalaya.
