Answer:(d) None
Green hydrogen does not play a significant role in decarbonizing any of the mentioned industries (fertilizer plants, oil refineries, and steel plants). While green hydrogen has the potential to contribute to decarbonization efforts in various sectors, its adoption and integration into industries are still limited and in the early stages. Other decarbonization strategies and technologies are currently more commonly used in these industries. Therefore, none of the industries listed significantly rely on green hydrogen for decarbonization.
