A major shift in the 8th Five-Year Plan from its preceding ones is

The Eighth Five‑Year Plan (1992–97) was launched after the 1991 structural adjustment and marked a departure from the earlier heavy emphasis on public‑sector-led heavy and basic industries toward supporting the liberalized economy by prioritising public investment in infrastructure and enabling sectors. Official summaries note the Eighth Plan’s timing with structural adjustment and an altered planning stance, indicating reorientation of public investment priorities to support growth and regional development [1]. The Plan documents and policy discussions also stress redefined roles for public undertakings, technology and industry intermeshing, and measures to bolster infrastructure and management practices to maximise returns on investments [3]. Hence option (2) best describes the major shift.
