A silhouette is best described as a dark outline against a lighter background. Which set of options best matches this concept?

• A. Bridge
• B. Skyscraper
• C. Kiln
• D. Silhouette

Answer: (D)

The idea being tested is that a silhouette is defined by a dark form that emphasizes its outer edge against a lighter background, with no internal details. A silhouette presents only the contour of a shape, filled in solidly, to highlight its overall form.

Among the options, the term that embodies this concept is the one that names such a form. The other options are specific real-world objects that typically include visible internal features and textures, rather than being defined by a strong outer outline against a light background. Therefore, the best match is the term that directly describes this kind of shape.
