Envisioning a developed India requires:

Concept

A developed nation needs durable indigenous capabilities that can convert knowledge into useful systems. Core technological strength means the domestic ability to design, adapt, produce, and sustain critical technologies over the long term.

Application

The stem asks for the foundational requirement for envisioning a developed India. Development of core technological strengths supplies the enduring domestic capability on which self-reliant economic and social development can be built.

Contrast and cross-check

• Aspiration to become a major economic player states a goal, but a goal by itself does not create the technical capacity needed to realise it.

• Dependence on projects designed abroad keeps critical design capability outside the domestic system and therefore cannot serve as the foundation of self-reliant development.

• A focus on short-term projects prioritises immediate outputs rather than the sustained capability-building required for national transformation.

• Development of core technological strengths creates the long-term domestic competence that directly meets the requirement in the stem.

Therefore, the required foundation is development of core technological strengths.
