What is silhouette of a shape related to?

Outer identity or outline of a shape

A silhouette is the outer visible shape of an object, usually shown as a solid, single-colour form without inner details. It tells us about the object’s external contour, posture, or overall identity. A familiar silhouette may be recognizable even when texture, colour, facial features, and internal lines are absent. Artists and designers use silhouettes to make strong, readable forms.

Option A is correct because silhouette is related to the outer identity or outline of a shape. Paper smell, picture sound, and brush weight do not describe an object’s contour. Internal details may improve recognition, but the silhouette depends mainly on the boundary between the object and the surrounding space. Thus, observing the outside edge is the key to understanding a silhouette.
