Consider the following information: Waterfall | Region | River 1. Dhuandhar | Malwa | Narmada 2. Hundru | Chota Nagpur | Subarnarekha 3. Gersoppa | Western Ghats | Netravati In how many of the above rows is the given information correctly matched?

Only the Hundru waterfall row is correctly matched — it is located in the Chota Nagpur plateau region and is formed on the Subarnarekha river. Dhuandhar Falls is on the Narmada river but located in the Bhedaghat area near Jabalpur in the Mahakaushal region (not Malwa plateau). Gersoppa Falls (also known as Jog Falls) is in the Western Ghats but is on the Sharavati river, not the Netravati. Thus only one row is correctly matched.
