Q. Karmanasa river originates in –
a) Patna District
b) Vaishali District
c) Kaimur District
d) Bikram District
Correct Answer: c) Kaimur District
Question from BPSC PT 71, 2025
Correct Answer: c) Kaimur District
Explanation:
– The Karmanasa River originates in the Kaimur Hills (Kaimur Plateau) located in Kaimur district of southwestern Bihar.
– From there it flows along the Uttar Pradesh–Bihar border and eventually joins the Ganga near Chausa (Buxar).
– Patna and Vaishali are in the Ganga plains, not hilly source regions, and “Bikram” is not a district. Hence, Kaimur District is the correct choice.
