b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed.

Explanation:

Some plants require more a of particular nutrient than others and so will draw more of these nutrients from the soil whilst giving away some of the ones that they do not want. This is one of the reasons that some plants grow better in a particular area than not.

When these plants give or take away nutrients, they would be changing the type of nutrient composition of the soil and this is what makes crop rotation so effective.
