Suppose you work for a government office that needs to find a suitable place to bury barrels of poisonous liquid wastes. the soils that are used to bury the waste should have properties that will prevent the liquid from moving quickly down toward the groundwater–just in case the barrels begin to leak at some point. you should look for a soil with which type of texture? sandy silty clay rich loam

The correct answer is clay rich soil

Explanation:

because the clay soil has high porosity than sand for example, as the porosity is inversely proportional with the grain size of the sediment . and the more porosity the soil has , the high amount of water that can be hold by it.

so the clay rich soil can hold high amount of water more than any sediment soil    

also the clay rich soil has a low permeability that means it rarely pass the water which it holds through it , because the clay is impermeable rock and the ability to pass liquids through its layer is very hard

So this is the good one

a is the correct answer
