In India which of the following Five Year Plan was launched with a focus on sustainable growth?

The answer is D (12th Plan). The 12th Five Year Plan (2012-17), approved by the National Development Council in December 2012, carried the theme "Faster, More Inclusive and Sustainable Growth". Sustainability was an explicit pillar, covering environment, energy efficiency and climate resilience.

• 9th Plan (1997-2002): theme was "Growth with Social Justice and Equity", with stress on human development and poverty removal.
• 10th Plan (2002-07): theme was "Accelerating Growth and Achieving Social Justice".
• 11th Plan (2007-12): theme was "Rapid and More Inclusive Growth". It stressed inclusion, but sustainability was not its headline theme.

The core concept is how planning vocabulary moved from social justice to inclusion to sustainability. Link this to Mains GS-3 on inclusive growth and environment. The Planning Commission was replaced by NITI Aayog on 1 January 2015, so there is no 13th Five Year Plan and the 12th remains the last one.

Trap: aspirants pick the 11th because "inclusive" sounds close to the sustainable theme, or they assume the most recent plan is the answer without checking the exact theme wording.
