B) colloid because i took the test and that the answer
The ability of solid rock to flow is called Plasticity.
Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.
Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set
I think B is the most correct, because logically it's harder to bend a stiffer spring than it is to bend a softer one. Also, I don't think length comes into play. So B.
