A Correct answer
Explanation

India's first supercritical thermal power plant (3x660 MW) was commissioned at Sipat in Chattisgarh in 2009 by NTPC. Supercritical technology operates at higher temperatures and pressures than subcritical plants, resulting in higher efficiency (around 45-47% compared to 38-40% for subcritical) and lower carbon emissions per unit of electricity generated.
