E Correct answer
Explanation

Ocean salinity is highest in arid regions due to high evaporation rates exceeding precipitation and freshwater input. Examples include the Red Sea (up to 41‰), Persian Gulf, and Mediterranean Sea where hot, dry conditions cause water to evaporate, leaving salts behind. The enclosed nature of these water bodies further concentrates salinity by limiting water exchange.
