A fractal is critical for comprehending the order that exists in chaos because:

a. It is the largest unit of organization that describes all elements that are subsets of something larger than itself.

b. A pattern of precise detail that appears repeatedly in the same pattern at every scale in a web of forever expanding symmetry.

c. An unnatural and chaotic discordant pattern of differentiation that does not repeat itself over time and space.

d. The smallest unit of organization that defines how all other units will operate and represents a fixed notion of system function and design.
