Explanation / Answer

Profile B is likely to have come from the subtropics. Dew point is the indicator of humidity. Greater dew point at a place with constant pressure and temperature means greater humidity at that place. The tropical region has higher humidity because insolation is higher and vast water bodies resulting in huge amount of evaporation.
