   Only one. Hundru on the Subarnarekha in Chota Nagpur is the clean row.

2. B

   Only two. Dhuandhar is Narmada but in the Satpura/Marble Rocks belt, not Malwa as labelled; Gersoppa is Sharavati, not Netravati.

3. C

   All three

   All three. Two rows are mismatches.

4. D

   None

   None. Hundru is correctly matched.

Summary. Official key is (a) only one. Hundru Falls: Subarnarekha, Chota Nagpur — correct. Dhuandhar is on the Narmada at Bhedaghat (Jabalpur), not in the Malwa region as the table says. Jog/Gersoppa is on the Sharavati in the Western Ghats, not the Netravati. So only row 2 matches.
