Explanation: The Ghaggar river, also known as the Ghaggar-Hakra river, is a seasonal river in northern India. It originates in the Shivalik Hills of Himachal Pradesh and flows through the state of Haryana before entering Rajasthan. The river is significant in the context of Haryana's geography and history, as it has played a crucial role in the region's agricultural and cultural development.
The Ghaggar river is often associated with the ancient Sarasvati River mentioned in the Rig Veda, an ancient Indian text. The river's course and significance have been a subject of archaeological and historical studies, particularly in relation to the Indus Valley Civilization. The river's seasonal nature means that it carries water primarily during the monsoon season and dries up during the rest of the year.
In terms of geography, the Ghaggar river flows through several districts in Haryana, including Sirsa, Bhatinda, and Fatehabad. It is an important source of irrigation for the agricultural lands in these regions. The river's course and the areas it covers are well-documented in geographical studies and maps of Haryana.
It is important to note that while the Ghaggar river does have a presence in parts of Punjab and Rajasthan, its primary course and significance are associated with Haryana. This is why option A is the correct answer. The river's flow through Punjab and Rajasthan is secondary to its primary course through Haryana.
Understanding the course of the Ghaggar river is essential for students studying the geography of Haryana and the broader region of northern India. It helps in comprehending the historical and cultural significance of the river and its impact on the region's development.
