Which statement best defines Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) in soil compaction?

Which statement best defines Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) in soil compaction?

• A. OMC is the moisture content at which dry density is maximum; MDD is the corresponding maximum dry density.
• B. OMC is the water content at which soil strength is minimized; MDD is the minimum density.
• C. OMC is the moisture content at which the soil becomes fully saturated; MDD is the density at saturation.
• D. OMC and MDD are independent of compaction effort and soil type.

Answer: (A)
