More evaporation means which of the following a. Less salinity and density b. More salinity and less density c. Less salinity and more density d. more salinity and more density

The answer is D. More evaporation means more salinity and more density. As the seawater evaporates, what's left is the salt and the fresh water is transferred from the ocean or sea to the atmosphere. The excess of the evaporation like the one in the subtropics which is more salty and the rainfall tends to be fresher.
