Explanation: The Narmada River is a significant geographical feature and a lifeline for Madhya Pradesh. Originating in the Amarkantak hills in Anuppur district of Madhya Pradesh, the Narmada flows westward through the state, forming a natural boundary between Madhya Pradesh and Gujarat. It is the fifth-longest river in India and is known for its unique course, as it flows from east to west, unlike most other major Indian rivers that flow from north to south.
The Narmada River is crucial for the state's agricultural economy. It supports a vast agricultural region, providing water for irrigation to millions of hectares of farmland. The river basin is home to a diverse range of crops, including rice, wheat, and various fruits and vegetables. The river's water is also used for drinking and domestic purposes, making it a vital resource for the local population.
In addition to its agricultural importance, the Narmada River is also significant for its cultural and religious significance. It is considered a sacred river in Hinduism, and many pilgrims visit the river for religious purposes. The river also supports a rich biodiversity, with various species of fish and other aquatic life thriving in its waters.
The Narmada River is also a source of hydroelectric power, with several dams and power plants constructed along its course. These power plants generate electricity, which is essential for the state's industrial and domestic needs.
In contrast, the Mahanadi River, while significant for the states of Odisha and Chhattisgarh, does not have a direct impact on Madhya Pradesh. The Mahanadi originates in the Dhamtari district of Chhattisgarh and flows through Odisha before emptying into the Bay of Bengal. It is not a major river in Madhya Pradesh and does not play a significant role in the state's economy or culture.
Therefore, the Narmada River is the correct answer as the lifeline of Madhya Pradesh, given its crucial role in the state's agricultural, economic, and cultural landscape.
