Confining pressure is where . Confining pressure is where . pressure is parallel to the bedding planes pressure is applied in a cubic region forces are applied from the top and the bottom equally forces are applied equally in all directions

d) Forces are applied equally in all directions

Explanation:

Confining pressures are pressures imposed on a layer of soil by the weights of the layers on top of it. Confining pressures occur as a result of equal transmission of forces between the layers of a material (usually rock and soil).

It can also be described as an equal, all-sided pressure produced by overlying rocks in the crust of the earth.  As the confining pressure increases, the critical elastic energy of the layers of the material transforms from linear to exponential.

the answer is a. hope this .
