Correct Answer: D — 3
Explanation:
The question asks for the basis of the palaeodrainage assertion.
Only statement 3 is correct. The presence of the same dolphin species in both the Indus and Ganga river systems is evidence of an older river connection or channel shift. Therefore, statements 1 and 2 are not correct.
