Materials that are not derived from living organisms are known as?

• A. Trench
• B. Spoils
• C. Plasticity index
• D. Inorganic

Answer: (D)

Materials not derived from living organisms are inorganic. Inorganic materials come from non-living processes—think minerals, metals, ceramics, glass, and concrete—things formed through geological or chemical processes rather than biological ones. This is opposite to organic materials, which originate from living matter or contain carbon-hydrogen bonds, like wood or plant-based substances. The other terms are not about origin: one refers to an excavation term, and the other to a soil property describing how a soil can deform. So the correct term for materials not from living organisms is inorganic.
