Who said there were three components? You need water vapour in the air. You need the air to be cooled below the dewpoint so that water droplets will condense to make the cloud so you need something to lift the air to cool it. You need minute particles of dust or salt called condensation nuclei onto which the water droplets will condense - and that's about it.
High level cloud is composed of ice crystals not water droplets and you need freezing nuclei rather than condesation nuclei onto which ice deposits straight from water vapour without going through condensation.
