The correct answer to this question is B.
Subtractive transformation is a process by which 3D objects are constructed by successively cutting material away from a solid block of material. Subtractive transformation can be done by manually cutting the material but is most typically done with a machine.
Advanced machines utilize multiple tools and cut around at least three (x, y, and z) axes such that they minimize the requirement for designers to flip the block. One of the principal advantages to subtractive transformation is the ability to machine an extremely thin piece of plastic into a living hinge.
NOTE: A form can be transformed by subtracting a portion of its volume. Depending on the extent of the subtractive process, the form can retain its initial identity or be transformed into a form of another family. For example, a cube can retain its identity as a cube even thought a portion of it is removed, or be transformed into a series of regular polyhedrons that begin to approximate sphere.
