Plasticity index. The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit (PI = LL-PL).

So, A is the right answer.

Yes, the correct answer is B.

B should be right answer.
