cloud is wrongly classified as cloud is not gas. you cannot see gas. instead, cloud is suppose to be classified as "liquid"
statement "... you cannot see gas ..." is incorrect generalization.
fact : most, but not all, gases are invisible.
common gases like oxygen, carbon dioxide, nitrogen, etc, are all invisible, but there are some substances like chlorine & bromine that are visible in their gaseous state. these are not within primary school science syllabus. but are covered in secondary school science.

Clouds are in semi- solid form and thus don't fit in any of the given groups. But they still are a form of water.
See 1 Answer
clouds are created when water vapour condenses. Thus clouds are actually formed by many water droplets and therefore it is actually liquid.
