Answer: A. Salty
Explanation: The salty adjective best reflects the salt water trait. More specifically if we use scientific vocabulary, a body of water with a high percentage of salt is called saline water or salinity. The salinity of water is determined by the amount of dissolved salt relative to the kilogram of water. Salt water, of course, is found in seas and oceans, although salt in very low percentage can be found in river water, or freshwater, but this percentage is insignificant.
