Match List-1 with List-II and select the correct answer using the codes given below the Lists

Dam | River
a. Ukai Dam | 1. Beas
b. Bhakra dam | 2. Krishna
c. Nagarjuna Sagar Dam | 3. Sutlej
d. Pandoh Dam | 4. Tapi (Tapti)

The correct answer is Option 3 (A-4, B-3, C-2, D-1) based on the geographical locations of these major river valley projects:

• Ukai Dam (A-4): Located in Gujarat, it is constructed across the Tapi River. It is the second-largest reservoir in Gujarat after the Sardar Sarovar.
• Bhakra Dam (B-3): This iconic gravity dam is built across the Sutlej River in Himachal Pradesh. It forms the Gobind Sagar reservoir.
• Nagarjuna Sagar Dam (C-2): Situated on the border of Telangana and Andhra Pradesh, this massive masonry dam is built across the Krishna River.
• Pandoh Dam (D-1): Located in Himachal Pradesh, it is an embankment dam on the Beas River, primarily used for diverting water to the Sutlej river basin for power generation.

Options 1, 2, and 4 are incorrect because they mismatch these established geographical pairings, such as incorrectly associating the Ukai dam with the Beas or the Bhakra dam with the Krishna river.
