Question

Which river is the largest southern tributary of the Ganga and joins it at Arrah in Bihar?

• A. Yamuna
• B. Son
• C. Chambal
• D. Rihand

Answer 1

Answer:

B. Son

• Correct Answer: Option A - Yamuna

• The Son River is the largest southern tributary of the Ganga (Ganges) River and joins it near Arrah in Bihar. While the Yamuna is the largest tributary of the Ganga overall, it joins the Ganga from the west at Prayagraj (Allahabad) in Uttar Pradesh. The Son River originates in the Amarkantak Plateau in Madhya Pradesh and flows northward through Madhya Pradesh, Uttar Pradesh, Jharkhand, and Bihar before joining the Ganga.

• The Son River is historically and geographically significant as it forms part of the important drainage system of the Gangetic plains and contributes significantly to the water volume of the Ganga. It is approximately 784 km long and has its own tributaries including the Rihand and the North Koel.

• Other major tributaries of the Ganga include the Yamuna (largest overall tributary), Gomti, Ghaghara, Gandak, and Kosi, but the Son stands out as the largest one joining from the southern side.
