Explanation

  1. A

    Only one

    Only one. Green hydrogen is discussed for all three heavy industries.

  2. B

    Only two

    Only two. Fertilizer, refining and steel are all hard-to-abate users of hydrogen / heat.

  3. C

    All three

    All three. Ammonia for fertilizer, refinery hydrogen, and steel DRI / heat.

  4. D

    None

    None. Each is a National Green Hydrogen Mission use-case.

Summary. Official key is (c) all three. Green hydrogen is expected to cut emissions in fertilizer (green ammonia), oil refining (process hydrogen) and steel (DRI / high-heat). None of the three is outside that map.
