Answer:
a. City A
Explanation:
City A has the highest saturation vapor pressure among other cities because it has highest temperature and dew point as compared to another cities. Temperature is related to saturation vapor pressure, if increase in the temperature occurs, the average energy of the particles is also increases. It means that more particles have enough kinetic energy to escape from the surface of the liquid as a result it increase the saturated vapor pressure and the region has the highest saturation vapor pressure.
