Contaminated soil can be rehabilitated by physical remediation methods, like aeration. What is another way soil can be treated to
transform soil for future generations?
A)Plant fungi, such as mushrooms.
B)Dig up and remove the topsoil layer.
C)Flush out the contaminants with an excessive amount of water.
D)Treat the soil with an excessive amount of phosphate based fertilizer.

C) Flush out the contaminants with an excessive amount of water.

Explanation:

Water is universal solvent. It dissolve many solutes inside it. Soil is contaminated with number of chemicals which is used by farmers for the controlling of pathogens. These chemicals remains on the soil for very long time. These chemicals are removed from the soil by applying high amount of water which flush out the chemicals from the soil.

Contaminated soil can be rehabilitated by physical remediation methods, like aeration. What is another way soil can be treated to  transform soil for future generations?

From the above analogy, another way the soil can be treated to transform soil for future use is by planting fungi such as mushrooms which helps to decompose any contaminants and digest them. This will enable the soil to be useful for future generation

Explanation:

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
