Option (D)
Explanation:
Evaporation is a process by which the liquid is converted into the gaseous state. This process occurs in certain parts of the ocean due to the presence of dry and warm wind in the regions where there is a lack of rainfall. This process leads to the elimination of the water and only the salt is allowed to remain. This results in the increasing salinity of the seawater and increases its density.
Thus, the salinity of the water increases after the process of evaporation takes place.
Thus, the correct answer is option (D).
