Given below are two statements:

Statement (I): International pipette method is regarded as the standard method for particle size analysis due to its accuracy.

Statement (II): The hydrometer method is rapid but less accurate.

In light of the above statements, choose the most appropriate answer from the options given below:

Correct option is A

Correct option: (a)
Why Statement (I) is true:
· The International pipette method is considered the reference/standard for particle size analysis.
· It provides high accuracy and reproducibility, especially for fine fractions (silt and clay).
Why Statement (II) is true:
· The hydrometer method is faster and simpler.
· However, it is less accurate due to assumptions about particle shape, temperature corrections, and suspension uniformity.
�� Key Points
· Pipette method → highest accuracy (standard method).
· Hydrometer method → rapid, routine use; slightly lower accuracy.
✔️ Final Answer: Option (a)
