Which of the following states is/are part of the Ganga Basin? 1. Chhattisgarh 2. Himachal Pradesh 3. Rajasthan Select the answer using the code given below:

The Ganga basin is the largest river basin in India, covering approximately 8.6 lakh sq. km, which is about 26.3% of the country's total geographical area [5]. It is an extensive drainage system that encompasses 11 states and the Union Territory of Delhi [5]. Specifically, Chhattisgarh is part of the basin as the Son river (a major right-bank tributary of the Ganga) drains portions of the state [1]. Himachal Pradesh is included because the Yamuna, the largest tributary of the Ganga, has catchment areas in the state [1]. Rajasthan is also a basin state because the Chambal river, which originates in Madhya Pradesh and flows through Rajasthan, is a major tributary of the Yamuna, which eventually joins the Ganga [4]. Therefore, all three states—Chhattisgarh, Himachal Pradesh, and Rajasthan—are integral parts of the Ganga basin [5].
