Correct answer: A. All (A), B. & C.
- A. All (A), B. & C.
- B. Liquefied & stored under cryogenic conditions
- C. Produced by electrolysis of water
- D. Used in I.C. engines as fuel
Explanation
Hydrogen can serve as fuel in internal-combustion engines, be liquefied and stored at cryogenic temperature, and be produced by electrolysis of water. Hence all three statements are valid.
