The Pradhan Mantri Gram Sadak Yojana (PMGSY) is a flagship rural-development programme launched on 25 December 2000. As the name literally translates — Gram (village) and Sadak (road) — its purpose sits squarely in the domain of rural roads.

Its primary goal is to provide all-weather road connectivity to eligible unconnected habitations in rural areas by constructing good-quality roads that remain usable in every season. This is why the option describing rural connectivity through road construction is correct.

Key features that reinforce this focus:

• It is a Centrally Sponsored Scheme targeting rural, not urban, areas.
• Coverage thresholds are population-based — habitations of 500+ persons in the plains, and 250+ in hill states, North-Eastern states, desert, and tribal areas.
• Beyond building new roads, later phases (PMGSY-II and III) also upgrade and consolidate the existing rural road network.
• Over the years it has added several lakh kilometres of rural roads, improving villagers' access to markets, schools, and healthcare.

The other options describe unrelated policy areas: urban infrastructure is the opposite of the scheme's rural focus; renewable energy falls under energy programmes, not a road-building scheme; and telecommunication services in cities concern digital/telecom initiatives, again urban and non-road in nature. None of these matches a programme whose very name and design centre on village road connectivity.
