Consider the following pairs :
1. Corbett National Park : Ganga
2. Kaziranga National Park : Manas
3. Silent Valley National Park : Kaveri
Which of the above pairs is/are correctly matched?

Correct Option: None

All three pairs are incorrectly matched. Corbett National Park is drained by the Ramganga river (a tributary of the Ganges), not the Ganga main stem itself. Kaziranga National Park lies along the Brahmaputra river, whereas the Manas river flows through Manas National Park. Silent Valley National Park in Kerala is drained by the Kunthipuzha river, which is a tributary of the Bharathapuzha river, not the Kaveri.
