Question

Arrange the following soil particles in descending order of their diameter:
• [(A)] Clay
• [(B)] Silt
• [(C)] Fine sand
• [(D)] Coarse sand Choose the correct answer from the options given below:

• A. A, B, C, D
• B. A, C, B, D
• C. D, C, B, A
• D. C, B, D, A

Hint:

Descending order of soil particle diameter: \[ \mathrm{Coarse\ Sand > Fine\ Sand > Silt > Clay} \]

Answer 1

The Correct Option is C

Step 1: Understand soil particle sizes.
Soil particles are classified according to their diameter. General order from largest to smallest: \[ \mathrm{Coarse\ Sand > Fine\ Sand > Silt > Clay} \]

Step 2: Arrange the given particles.
\[ \mathrm{Coarse\ Sand} \] has the largest diameter. \[ \mathrm{Fine\ Sand} \] is smaller than coarse sand. \[ \mathrm{Silt} \] is finer than sand. \[ \mathrm{Clay} \] has the smallest particle size. Thus: \[ D > C > B > A \]

Step 3: Identify the correct option.
Therefore: \[ \boxed{D,\ C,\ B,\ A} \] Hence, the correct answer is: \[ \boxed{\mathrm{(C)}} \]
