Concept:The Sone River originates from the Amarkantak Hill in Madhya Pradesh, which is also the source of the Narmada River.
Explanation:The Sone River begins near the Gaurela-Pendra-Marwahi district of Madhya Pradesh.
It is the second-largest southern tributary of the Ganges and flows for about 784 km.
The river joins the Ganges near Patna, Bihar.
A famous landmark, the Koilvar Bridge (India’s oldest river bridge), spans the Sone near Ara in Patna.
The Sone is also mentioned in the ancient Tamil work “Kuruntokai” (2nd century BCE).
Other options do not match:
- Parasnath Hill (Giridih, Jharkhand) is a Jain sacred site (Sammed Shikhar).
- Trikut Hill (Jharkhand) has three peaks (Trikutachal) with elevation ~2470 ft.
- Morabadi Hill (Ranchi, Jharkhand) is also called Tagore Hill, about 300 ft high.
