Explanation

The Green Revolution (from the 1960s) was based on the 'seed–fertiliser–water' package: high-yielding variety seeds, chemical fertilisers, and assured irrigation. Mechanical equipment (option B) characterised farm mechanisation rather than the Green Revolution itself, financial assistance (option C) was not its technological core, and organic manures (option D) were displaced by chemical fertilisers. Hence the seed–fertiliser–water technology is the correct answer.
