The Mahanadi basin does not extend over which state?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Karnataka.
The Mahanadi River basin is one of the major river basins in India, primarily spread across the states of Chhattisgarh and Odisha. It also covers smaller portions of Maharashtra, Jharkhand, and Madhya Pradesh. However, it does not extend over the state of Karnataka. The Mahanadi originates from the Sihawa Hills in Chhattisgarh and flows eastward into the Bay of Bengal. Since Karnataka lies to the southwest of this region and is not part of the Mahanadi’s drainage system, it is not included in the Mahanadi basin. Hence, Karnataka is the correct answer.
