Which phenomenon causes eastern boundary currents to have slower speeds?

💡 Explanation

Wind forcing along continental coasts, intensified by the Coriolis effect, causes Ekman transport (upwelling) pulling deep water upwards; because of this, temperature stratification limits the current speed rather than driving it forward. Therefore, option A is correct.
