Why is the 'Pumped Storage Hydroelectric Project' (PSP) considered crucial for India's non-conventional energy expansion plan?

Options:

• A: It acts as a giant water-based battery that stores excess solar/wind energy during off-peak hours and releases it during peak demand.
• B: It generates electricity continuously without requiring any external water source or initial energy input.
• C: It is the only method to extract geothermal energy from deep riverbeds.
• D: It completely eliminates the need for transmission lines by generating power directly at the consumption site.
