Explanation: The Ganga River, also known as the Ganges, is one of the most significant rivers in India, both culturally and geographically. It originates from the Gangotri Glacier in the Himalayas and flows through several states before emptying into the Bay of Bengal. Understanding the course of the Ganga and its tributaries is essential for various competitive examinations.
The Ganga River begins its journey in the Himalayas and flows through the states of Uttarakhand, Uttar Pradesh, Bihar, and West Bengal. It does not pass through Madhya Pradesh. The river enters the plains at Haridwar, not at Devprayag. Devprayag is the confluence of the Bhagirathi and Alaknanda rivers, which together form the Ganga. This confluence is a significant pilgrimage site in Hinduism.
The Ganga has several tributaries, both on the left and right banks. The Son is indeed a major left bank tributary of the Ganga. It originates in the Amarkantak Plateau in Madhya Pradesh and joins the Ganga in Bihar. Other major tributaries include the Yamuna, which joins the Ganga at Allahabad, and the Ghaghara, which is a right bank tributary.
It is important to note that the Ganga's course and tributaries are often a subject of confusion. The confluence at Devprayag is often mistaken for the point where the Ganga enters the plains, but this is incorrect. The Ganga enters the plains at Haridwar, where it begins its journey through the Gangetic plains.
In summary, the correct understanding of the Ganga's course and tributaries is crucial for students preparing for competitive examinations. The Ganga does not enter the plains at Devprayag, it does not pass through Madhya Pradesh, and while the Son is a major left bank tributary, the other statements are incorrect. Therefore, the correct answer is that none of the statements are entirely correct.
