Model Answer

Option B — Each purchaser chose a different painting school to hand-illuminate the borders and illustrations, making every copy unique.

Source: Gutenberg and the Printing Press, Chapter 5

Explanation

The passage explicitly states: "Each purchaser could choose the design and decide on the painting school that would do the illustrations," and "No two copies were the same." The text was mechanically printed, but borders and illustrations were painted by hand differently for each copy. Options A, C, and D are not mentioned anywhere in the source.
