I know hydrogen is the correct answer but anybody tell me why water vapour is considered as a greenhouse gas?

@Ankur.

When water evaporates the steam of the water is carbon dioxide that is why water vapour is considered as a greenhouse gas.

Hydrogen is not a greenhouse gas and water vapour is a greenhouse gas.

Hydrogen gas is not known as grenhouse gas.

Hydrogen (H2) is similar to carbon monoxide in that it acts as an indirect greenhouse gas through its effect on hydroxyl (OH) radicals. By reducing the levels of OH in the atmosphere, hydrogen increases the lifetime of some direct greenhouse gases, such as methane.

The greenhouse gases make a layer on the earth's surface that traps heat in it thus making the earth warm.
