The Polavaram Irrigation Project, which has been in the news recently, is located in Andhra Pradesh. It is important to note that while the correct answer is Andhra Pradesh, the other options listed (Karnataka, Kerala, Tamil Nadu) are incorrect.

Andhra Pradesh is a state in the southeastern part of India, and the Polavaram Irrigation Project is a major undertaking in this region. This project involves the construction of a dam across the Godavari River near the village of Polavaram. The primary objective of this project is to provide irrigation water to the drought-prone areas of Andhra Pradesh and also generate hydroelectric power.

It is essential to understand that location-based questions like this one require knowledge of specific geographical details. In this context, knowing that the Polavaram Irrigation Project is located in Andhra Pradesh helps us better understand the significance of the project and its implications for the region`s agriculture and power generation.
