Explanations:The Narmada River is a significant river in India, flowing through the state of Madhya Pradesh. It is often referred to as the "lifeline" of Madhya Pradesh due to its crucial role in agriculture, water supply, and economic activities. The Narmada originates in the Amarkantak hills in Anuppur district of Madhya Pradesh and flows westward through the state, forming a natural boundary between Madhya Pradesh and Gujarat. It eventually drains into the Arabian Sea.
The river is approximately 1,312 kilometers long and is the fifth-longest river in India. It is one of the most sacred rivers in Hinduism and is considered a goddess. The Narmada River basin is home to a diverse range of flora and fauna, and the river itself supports a variety of aquatic life. The river's water is used for irrigation, drinking, and industrial purposes, making it a vital resource for the state.
The Narmada River also plays a significant role in the state's economy. It supports agriculture, which is a major economic activity in Madhya Pradesh. The river's water is used to irrigate vast tracts of agricultural land, ensuring food security for the region. Additionally, the river is a source of hydroelectric power, with several dams and power plants constructed along its course.
Given its importance in providing water for agriculture, drinking, and industrial use, the Narmada River is rightly considered the lifeline of Madhya Pradesh. The Mahanadi River, on the other hand, is not a major river in Madhya Pradesh; it primarily flows through the state of Odisha. Therefore, it cannot be considered the lifeline of Madhya Pradesh.
In conclusion, the Narmada River is the correct answer as it is the primary river that supports the economic and ecological needs of Madhya Pradesh, making it the lifeline of the state.
