D. *Verification stage.* Although the conception is abstract in nature, the idea must be subject to logical analysis and reality testing. Is it really possible to make a book without ink but for it to still be comprehensible to readers? Previous examples of books without ink such as Braille must be retrieved from memory and other external sources to verify the plausibility of the current idea.
