The correct answer is A. A picture showing forests being cut down
Explanation:
A brochure is a type of paper that aims at providing information about one specific issue or subject in a concise way and by using elements such as diagrams, bulleted lists, and images. In the case of using images, as any of the other elements in the brochure they need to explain or support the main topic or idea. This implies in the case of a brochure that focuses on using cloth napkins to protect the environment, the image will need to explain one or more reasons to use this type of napkins and therefore, the best image, in this case, is "A picture showing forests being cut down", because this directly shows by using napkins the areas of forest that are cut down would reduce which means it supports the main topic or idea of the brochure and therefore is the most appropriate image.
