Correct option is C
Vijayawada's location on the banks of the Krishna River plays a significant role in the city's geography, economy, and even culture. The Krishna River, India's second-longest river after the Ganges, flows through the heart of Vijayawada. The Indrakeeladri Hills on the eastern side and the river on the western side create a picturesque setting for the city. The Prakasam Barrage, built across the Krishna River, regulates water flow and provides irrigation to agricultural lands in the surrounding areas.
