The correct answer is d) Salinity

Explanation:

Salinity is the content of mineral salts dissolved in a body of water and found at medium altitudes. The salty taste of water is due to the fact that it contains sodium chloride (NaCl). Its concentration in the seas and oceans is very high between 33 and 37 g / L and very low in freshwater. For its part, in water bodies with higher salinity, it is possible to float more easily.
