An illustration or photograph can be used, referred to, or consulted as a source of information only if it

• A. Provides words or an explanatory text that accompanies the illustration
• B. Is colorfully presented
• C. Is copyrighted
• D. Is printed on glossy paper

Answer: (B)

Colorful presentation helps readers interpret visual information. When an illustration or photograph uses color effectively, it makes distinctions between different parts easier to see, highlights relationships, and clarifies trends or categories. This kind clarity is what makes an image useful as a source of information, so a colorfully presented image often communicates meaning more efficiently than a dull, monochrome one.

As for the other possibilities, an image can be informative even without text accompanying it, copyright status doesn’t determine whether something can be used as a source (it just affects how you can reuse it), and the type of paper or printing quality doesn’t change the information the image conveys.
