Which option shows a weak silhouette that will reduce shape readability?

Blurred outer boundary merging with background

A silhouette is the visible outer contour or overall outline of a shape. Viewers often recognize an object from this outline before they notice its internal details. A strong silhouette has a clear boundary and enough contrast from the background. A weak silhouette may be blurred, broken, or so similar to the background that its edge becomes difficult to follow. In that case, the shape is harder to read quickly.

Option B is correct because a blurred outer boundary merging into the background reduces the difference between object and surroundings. The eye cannot easily decide where the object begins or ends, so recognition becomes weaker. A clear outline, a clean edge, and good contrast support readability, as shown by the other options. A silhouette does not need to be detailed; it mainly needs a sufficiently distinct outer contour for the intended subject to remain understandable.
