Concept:The dew point is the temperature at which air becomes saturated, and it depends on moisture content and pressure rather than the current temperature of the air.Explanation:The dew point is influenced by the amount of water vapour in the atmosphere.It is also affected by atmospheric pressure.Wind does not directly determine the dew point.A change in the temperature of the air does not change the dew point, provided the water vapour content and pressure remain constant.Therefore, temperature is the factor that does not affect the dew point.Answer:A. temperature
