3 (b) Sorry, not a correct choice. However unusual the choice of colors, forms and pattern may be, this sofa is not an attempt to imitate some other form or object. Therefore the materials are used honestly, presented for what they are.

But the pair of pitchers shown below illustrate the difference between honest and dishonest use of materials. Using the precious material-- silver-to imitate the humble material - wood is hard to justify. The form is natural to the construction of the wooden pitcher, but is merely a surface decoration in silver "pretending" to be wood.
