Soils are classified into different categories based on their properties and characteristics. The classification system you're referring to seems to be related to the USDA Soil Taxonomy system. In this system, the classes are typically Roman numerals (I, II, III, etc.), and each class has its own set of characteristics and limitations.
To answer your question, the class of soils that is not likely to erode but has other limitations that are impractical to remove and limit their use is typically Class VII. Class VII soils are referred to as "Miscellaneous" soils, and they often have limitations that make them unsuitable for most agricultural or construction purposes. These limitations can include factors like extreme rockiness, excessive steepness, severe wetness, or shallow rooting depth. While they may not erode easily, their other limitations make them impractical for many uses.
So, the correct answer to your question is:
D. VII
