Recently, linking of which of the following rivers was undertaken?

Discusses the National River Linking Project, government spending and a 2016 newspaper reference about interlinking plans and challenges.

A student could check whether specific links involving Cauvery–Tungabhadra are listed under NRLP proposals and whether any implementation milestones were reported around 2016.

Notes public discussion in NCERT about 'linking of rivers' and highlights technical difficulties (terrain, lifting water) for transferring water from northern rivers to peninsular rivers.

Use this to infer that any peninsular inter-basin link (including Cauvery–Tungabhadra) faces engineering/terrain hurdles; check project feasibility/status reports for 2016.

Describes a major planned inter-basin scheme (Ganga–Kaveri Link) that would route water to southern basins via barrages, lifts and canals—an example of large, multi-decade linking projects.

Compare the scale and timeline of the Ganga–Kaveri proposal with any Cauvery–Tungabhadra linkage claims to judge whether a recent (2016) completion is plausible.

Shows another example (Brahmaputra–Ganga link) where international/financial and political issues prevented start of works despite proposals.

Use this pattern (proposals delayed by diplomacy/finance) to assess whether a smaller peninsular link would likely have been completed by 2016 or still be pending.

Gives factual location/role of the Tungabhadra (a Krishna tributary) and existence of an established Tungabhadra dam and canals—context on existing infrastructure that could matter for linking works.

A student could map the Tungabhadra’s known infrastructure and the Cauvery basin to see whether a new interlink canal would be short/complex and therefore likely or unlikely to have been executed by 2016.
