Explanation: The Narmada River is the largest river in Gujarat, flowing from east to west through the state. It originates in the Amarkantak Plateau in Madhya Pradesh and traverses a distance of approximately 1,312 kilometers before emptying into the Gulf of Khambhat in the Arabian Sea. The Narmada is a significant river not only for Gujarat but also for Madhya Pradesh, where it forms a major part of the state's geography.
The Narmada River is known for its ecological and economic importance. It supports a diverse range of flora and fauna and is a crucial source of water for irrigation, drinking, and industrial purposes. The river basin is home to several important cities and towns, including Bharuch and Vadodara in Gujarat.
In contrast, the Sabarmati River, while significant, is much shorter and has a smaller drainage basin. It flows through Ahmedabad and is known for its historical and cultural significance, particularly in relation to the Indian independence movement. The Tapi River, another major river in Gujarat, flows through the western part of the state and is important for agriculture and industry, but it is not as large as the Narmada.
Understanding the major rivers of Gujarat is essential for comprehending the state's physical geography and its impact on the region. The Narmada's size and importance make it a key feature of Gujarat's landscape and a vital resource for the state's economy and ecology. Therefore, the Narmada is the correct answer as the largest river in Gujarat.
