option A and B are out of context
option D tells us information about external factors affecting the income
option E is giving irrelevant information
option C clearly points the flaw in reasoning that if the painter produces painting of inferior because she decides to cut costs by using cheaper paints and canvases there will clearly a drop in sales
so correct answer - C
