3 (a) No, this is not a correct answer. No matter how unusual this sofa may be in form and decoration, there is nothing about its appearance that would make it uncomfortable to sit on, which is its function- even though you might not choose to have something that looks like this in your living room.

On the other hand, the image below of a novelty telephone surely is an example of form that does not serve the function, not to mention the concept or idea of pressing this "phone" against one's cheek!
