The Correct answer is Failure of the Third Five-Year Plan. Explanation & Key Takeaways: • The Third Five-Year Plan (1961–1966) in India aimed at achieving self-sufficiency in food production and increasing industrial output. • However, the plan faced severe challenges due to events such as the India-China War in 1962, the India-Pakistan War in 1965, and a series of droughts that resulted in food shortages. • The plan failed to achieve its goals, leading to substantial economic setbacks and a decline in agricultural production. • Due to these challenges, the government decided to suspend further Five-Year Plans temporarily, resulting in the 'Plan Holiday' period from 1966 to 1969. • During this period, annual plans were formulated instead of long-term Five-Year Plans to focus on immediate issues such as food production, economic stabilization, and post-war recovery. • The Plan Holiday was essential to address the economic crisis and reevaluate strategies for future planning in India. Related Concepts: • Political instability • Political instability can affect economic planning, but it was not the primary reason for the Plan Holiday. The Plan Holiday was more a response to economic challenges and failures of the Third Five-Year Plan. • Political instability in India during the 1960s was marked by leadership changes, such as the transition from Jawaharlal Nehru to Lal Bahadur Shastri, and later to Indira Gandhi, but this was secondary to the economic issues. • Economic liberalisation • Economic liberalisation refers to the process of reducing government restrictions on the economy, which gained prominence in India during the 1990s, not the 1960s. • It was not related to the Plan Holiday, as the focus during this time was on addressing immediate economic crises rather than liberalisation. • Deflation • Deflation refers to a decrease in the general price level of goods and services. While economic issues were part of the challenges, deflation was not the direct reason for the Plan Holiday. • The Plan Holiday was more focused on managing food shortages and economic instability caused by droughts and wars.
