Answer 1

Answer: b.  They are produced on white paper

Blueprint is a reproduction of an architectural plan or an engineering design. It was originally done by using a contact print process on light-sensitive sheets, and it was characterized by white lines on a blue background.

Traditional blueprints became obsolete when less expensive printing methods became available. They were replaced by whiteprints, which resulted in blue lines over a white background. They remained in use until they were replaced by xerographic print processes.
