Which of the following is NOT one of the four primary explicit goals of five-year plans?

The correct option is Education.

Explanation:
The five-year plans were formulated with four primary explicit long-term goals that formed the foundation of economic planning and development:

1. Growth: Increasing the economy's capacity to produce goods and services.
2. Modernisation: Adopting new technologies and updating social outlooks to boost productivity.
3. Self-reliance: Avoiding excessive dependence on imports and foreign aid by producing essential goods domestically.
4. Equity: Ensuring equitable distribution of wealth so that the benefits of growth reach all sections of society and reduce inequality.

Although Education is an essential component of human resource development and social infrastructure, it is categorized as a specific sectoral target rather than one of the four main overarching goals of the five-year plans. Hence, Education is NOT one of the four primary explicit goals.
