The correct option is B Dew
The
droplets of water deposited on any cool surface by condensation of water vapour
in atmosphere are known as dew. When temperature drops and objects cool down,
dew is formed. The temperature at which dew forms is called the dew point. Location,
weather, and time of day affect the dew point. Dew is more likely experienced
by the humid areas than arid areas. It is mostly formed at night.
