Explanation:

Only statements 2&3 are correct.

Recently, the World Economic Forum (WEF) ranked India at 135 out of 146 countries in its Global Gender Gap (GGG) Index for 2022. 

• India’s overall score has improved from 0.625 (in 2021) to 0.629, which is its seventh-highest score in the last 16 years.
• In 2021, India was ranked 140 out of 156 countries.
• The gender gap is the difference between women and men as reflected in social, political, intellectual, cultural, or economic attainments or attitudes.

The index benchmarks the current state and evolution of gender parity across four key dimensions. These dimensions are:

• Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment.

On each of the four sub-indices as well as on the overall index the GGG index provides scores between 0 and 1, where 1 shows full gender parity and 0 is complete imparity.

• It is the longest-standing index, which tracks progress towards closing these gaps over time since its inception in 2006.

Hence option 2nd is correct.
