Water clarity is measured in units of

acidity
conductivity
salinity
turbidity

The correct answer is: acidity

Explanation Water clarity refers to the degree of transparency or translucency of water. It is measured by the amount of light that is able to penetrate the water. The unit used to measure water clarity is called a formazine turbidity unit (FTU). Options B, C, and D are not units of measurement for water clarity. Acidity refers to the level of acidity in water, conductivity refers to the ability of water to conduct electricity, and salinity refers to the concentration of salt in water. Only option D, turbidity, is a measure of water clarity. Therefore, A is the correct answer.
