Statement (A) is true; India ranks fourth globally in terms of installed wind power capacity as of recent data (e.g., early 2024). Statement (C) is true; according to assessments by the National Institute of Wind Energy (NIWE), Gujarat has the highest estimated wind power potential at 100m above ground level among Indian states. Statement (B) is false; the total wind power installed capacity in India is around 45-46 GW as of early 2024, not 400 GW. 400 GW is closer to India's total power generation capacity from all sources, or significantly higher than India's current total renewable capacity.
