The base of a cumulus cloud is determined by the altitude at which the air temperature cools to the dew point temperature, causing condensation. A smaller difference between the air temperature and the dew point temperature (as in option C) means the air does not have to rise as much to cool to the dew point, resulting in a lower cloud base.
