Ocean water is most saline a. where rivers empty into the ocean. b. in dense seawater. c. near coastal areas with high rainfall. d. in icebergs.

The term salinity denotes the total amount of dissolved salts in a liquid sample.  For example, the salinity of the ocean water was much greater than the salinity of the lake water.

Ocean water is most saline  in dense seawater. Correct B

Coastal waters on the other hand in cool, humid areas where fresh water rivers run into the ocean tend to have lower salinity.
