Correct Answer: Option B — 2 and 3 only
Detailed Explanation of the Statements: Statement 1 is INCORRECT: The process described here—extracting hydrogen from natural gas (methane) through steam methane reforming but capturing and storing the resulting carbon emissions—defines Blue Hydrogen.Statement 2 is CORRECT: Green Hydrogen is strictly defined by its zero-emission production method. It is produced by splitting water ($H_2O$) into hydrogen and oxygen through a process called electrolysis, powered entirely by renewable energy sources like solar or wind power.Statement 3 is CORRECT: Under the National Green Hydrogen Mission launched by the Government of India, one of the primary targeted outcomes by the year 2030 is the abatement of nearly 50 MMT (Million Metric Tonnes) of annual greenhouse gas emissions, alongside building a production capacity of at least 5 MMT per annum.
