There can be no categories without classification. Which statement best expresses this idea?

• A. Categories require no organization
• B. Categories exist without labels
• C. Classification is optional for grouping
• D. Classification is necessary for categorization

Answer: (D)

The main idea here is how we create groups. To have categories, you must first classify things—that is, decide which items share features and belong in the same group. When classification happens, the resulting groups become categories. So the statement that classification is necessary for categorization expresses that dependence clearly. It's not accurate to say categories require no organization, because forming categories is a way of organizing. It's also not correct to say categories exist without labels, since naming the groups is part of recognizing and using them. And it isn't correct to say classification is optional for grouping, since without classification you wouldn't have well-defined categories to group into.
