Answer:
option 2 The salinity is so high, because the rate of evaporation is high, and the rate of rainfall is low.
Step-by-step explanation:
Since the rate of evaporation is high the water evaporates in the form of vapours and it will not carry salt with it.
And while the rainfall that is occurring in that place is less than the rate of evaporation.
meaning there will not be enough water to dilute the salinity meaning there will be alot more salinity in that ocean.
