Inorganic soils with low compressibility are represented by

Answer: Option C

The correct answer is C: ML.
Let's break down why:
Soil Classification: In soil mechanics, we use a system to classify different types of soil. This helps us predict how the soil will behave.
Inorganic vs. Organic Soils: Inorganic soils are made of minerals, like sand, silt, and clay. Organic soils contain a lot of decomposed plant and animal matter.
Compressibility: Compressibility refers to how much a soil's volume decreases under pressure. Low compressibility means the soil doesn't shrink much when you put weight on it.
The Options Explained:
MH: This represents inorganic silts with high compressibility.
SL: This is not a standard soil classification symbol.
ML: This represents inorganic silts with low compressibility. This is exactly what the question is asking for!
CH: This represents inorganic clays with high compressibility.
Therefore, ML (inorganic silts with low compressibility) is the right answer.
