A Correct answer
Explanation

Trade winds blow from east to west in the tropical zone, causing upwelling of cold, less saline water along western coasts and piling up of warm, more saline water along eastern coasts. This makes salinity higher in eastern coastal areas. Both the assertion and reason are correct, and the reason properly explains the assertion.
