Incorrect Options
Row 1: Dhuandhar Waterfall is situated in the Jabalpur district of Madhya Pradesh and is formed by the Narmada River. However, the region where Jabalpur is located is Mahakoshal, not Malwa. The Malwa plateau lies to the northwest of the Vindhyas, while Mahakoshal is to the southeast, encompassing Jabalpur. Therefore, the region is incorrectly matched.
Row 3: Gersoppa Waterfall, also known as Jog Falls, is located in the Shimoga district of Karnataka, within the Western Ghats. It is formed by the Sharavathi River, not the Netravati River. Hence, the river name is incorrectly matched.
