A
The amount of salt dissolved within a substance, generally referring to the salt content of water or soil.
B
How salty a person may become when you offend them
C
The amount of water compared to salt in a solution
D
The amount of salt dissolved in water
Explanation: 

Detailed explanation-1: -Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity ). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰).

Detailed explanation-2: -The term “salinity” refers to the concentrations of salts in water or soils.

Detailed explanation-3: -It is written as 35 ‰ The normal range of ocean salinity ranges between 33-37 grams per liter (33‰-37‰). But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity.

Detailed explanation-4: -Soil salinity is the amount of dissolved salts in the soil solution (the aqueous phase in the soil). The process of accumulating soluble salts in the soil is known as salinization. Salts in the soil have an important effect on the functions and management.

Detailed explanation-5: -Salinity is the amount of dissolved salts or ions in seawater. The unit of measurement is grams of salt per 1000 grams of seawater or simply parts per thousand (written as ‰).
