Solution

The correct option is D water
Coke is an amorphous allotrope of carbon (C). When steam (H2O) is passed over red hot coke, then a mixture of carbon monoxide (CO) and hydrogen (H2) gas is formed. This gas is called water gas.
  • Natural gas is methane (CH4) and is produced when plant and animal matter decomposes anaerobically.
  • Producer gas is a mixture of carbon monoxide, nitrogen and hydrogen gas. It is obtained when steam mixed with air is passed through red hot coke.
  • Industrial gases are manufactured for use in various industries. For example, hydrogen, helium, etc.
