Question

Textural classifications are merely based on

• A. Consistency limit
• B. Grain size
• C. Grain size and plasticity index
• D. Elasticity index

Hint:

Soil classifications: \[ \boxed{ \begin{aligned} \text{Textural Classification} &\rightarrow \text{Grain Size} \text{Unified Classification} &\rightarrow \text{Grain Size + Plasticity} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall textural soil classification. Textural classification groups soils according to the relative proportions of sand, silt, and clay particles.

Step 2: Identify the basis of classification. Since it depends only on particle size distribution, \[ \boxed{\text{Grain size}} \] is the basis of textural classification. Hence, \[ \boxed{(B)} \] is the correct answer.
