Option 1 states that Pandharpur is located on the River Chandrabhaga and Tiruchirappalli is located on the River Cauvery. This is correct, as Pandharpur indeed lies on the bank of River Chandrabhaga in Maharashtra, and Tiruchirappalli, also known as Trichy, is situated near the River Cauvery in Tamil Nadu.

Option 2 suggests that Tiruchirappalli is located on the River Cauvery and Hampi on the River Malaprabha. This is partly correct as Trichy is indeed situated by the River Cauvery, however, Hampi is situated on the bank of the Tungabhadra River, not Malaprabha.

Option 3 suggests that Pandharpur is located on the River Chandrabhaga and Hampi is located on the River Malaprabha. This is partially correct, as Pandharpur does sit by River Chandrabhaga, but again, Hampi is on Tungabhadra River.

Option 4 includes all three pairings, which is incorrect as Hampi is not situated on the River Malaprabha. Hence, option 1 is the correct answer.
