Solution

The correct options are
B The combustion hydrogen does not produce polluting emissions of CO, $C O_{2}$ , oxides of nitrogen, and sulphur, aldehydes etc.
C The technology required for use of hydrogen fuel is simple and cost effective.
The following are the advantages of using hydrogen as an automobile fuel.
The amount of energy released per unit weight of the fuel is very high.
The combustion hydrogen does not produce polluting emissions of CO, $C O_{2}$ , oxides of nitrogen, and sulphur, aldehydes etc. Here, combustion product of hydrogen is water with few traces of nitrogen oxides. So no pollution is caused.
The technology required for use of hydrogen fuel is simple and cost effective.
The fuel cells using catalytic combustion of hydrogen have efficiency of 70-80 percent.
