Consider the following pairs:

Which of the pairs given above is/are correctly matched?
- A(I), (II) and (IV)
- B(II) only
- C(II) and (IV)
- D(I) and (III)
Solution & Step-by-step Explanation
Let us evaluate each pair individually:
* (I) Rihand Dam: Located across the Rihand River in Sonbhadra district, Uttar Pradesh. (Correct)
* (II) Massanjore Dam: Built across the Mayurakshi River and physically situated in the Dumka district of Jharkhand (though funded and managed historically by West Bengal for irrigation purposes). (Incorrect match for physical state location)
* (III) Rana Pratap Sagar Dam: Constructed across the Chambal River in Rawatbhata, Rajasthan. (Correct)
* (IV) Hirakud Dam: One of the longest earthen dams, built across the Mahanadi River in Sambalpur, Odisha, not Chhattisgarh. (Incorrect)
Hence, only pairs (I) and (III) are correctly matched.
