An author presents a variety of information about a particular subject.

• A. Facts
• B. Opinions
• C. Classification
• D. Inferences

Answer: (C)

Classification means organizing information by putting related items into groups based on shared characteristics. When an author presents a variety of information about a subject, they often arrange those details into categories—such as definitions, examples, causes, effects, or types—so the material fits together and the subject becomes easier to understand. This kind of organization shows how different pieces relate to one another, which is exactly what classification does.

While a writer might include facts, opinions, or inferences, simply listing or presenting different pieces of information doesn’t inherently show the category-based grouping that classification highlights. The emphasis here is on how the information is organized into meaningful groups rather than on the individual statements, beliefs, or conclusions themselves.
