Answer:
Precipitation
Step-by-step explanation:
Although the options are missing in the question, one word that can be solely used for rain, sleeet, snow and hail is "preciptation".
Principally, precipitation is a meteorological phenomenon that allows the condensation of atmospheric water vapors to make them fall on the Earth's surface under gravity. It is important to consider that fog and frost couldn't be considered as precipitation because, in these processes, water vapours don't fall on the Earth's surface.
