निम्नलिखित कथनों में से कौन-सा एक, विभिन्न हितधारियों को जल का उचित और साम्यिक बंटवारा सुनिश्चित करने के लिए सर्वाधिक युक्तयुक्त, व्यावहारिक और सर्वोत्तम रूप से प्रतिबिंबित करता है ?

Correct Option: A national, pragmatic, legal and policy framework for water allocation should be made.

The passage highlights that water is a State subject with inter-State river regulation under the Union, and increasing water stress requires a basin-based approach considering objective criteria such as dependent population, river basin specificities, and environmental needs. To implement this uniformly and equitably across competing States and regions, a macro-level structured legal, policy, and administrative framework at the national level is the most rational, practical, and immediate structural action. Other options like interlinking all rivers or massive canal creation are ecologically and economically extreme or impractical, while merely reducing sector demand does not address the institutional allocation mechanism. Thus, option (a) is the correct reflection of the passage's core message.
