The correct answer is option (d), 4 2 1 3.

Let`s analyze each option:

Option (a) suggests that Gandhi Sagar Dam is across the Bhagirathi River, which is incorrect. The correct answer is that Gandhi Sagar Dam is across the Chambal River, so option (a) is incorrect.

Option (b) suggests that Jayakwadi Dam is across the Krishna River, which is incorrect. Jayakwadi Dam is actually across the Godavari River. Therefore, option (b) is incorrect.

Option (c) suggests that Nagarjuna Dam is across the Godavari River, which is correct. However, Tehri Dam is across the Bhagirathi River, not Jayakwadi Dam. Therefore, option (c) is incorrect.

Option (d) suggests that Tehri Dam is across the Chambal River, which is correct. It also correctly states that Jayakwadi Dam is across the Godavari River and Gandhi Sagar Dam is across the Krishna River. Therefore, option (d) is the correct answer.
