B. Icebergs melting
Melting icebergs contributes to a low salt concentration (salinity) in the oceans because they are primarily composed of freshwater. When icebergs melt, they release freshwater into the surrounding seawater, diluting the seawater's salinity.
In contrast, evaporation (option A) typically increases salinity because when seawater evaporates, the water vapor leaves the salts behind, resulting in higher salinity in the remaining water.
