Which statement best describes the difference between framed and unframed symbols?

• A. Framed symbols indicate one unit type
• B. Framed symbols have color-coded borders
• C. Framed symbols rely on grid coordinates
• D. Framed symbols include a border around the symbol, while unframed symbols do not.

Answer: (D)

Framed symbols are defined by the border around the symbol. That outer border is the key feature that sets framed symbols apart from unframed ones, which appear without any enclosing edge. This border helps with quick visual isolation and consistent interpretation on maps, especially when symbols are close together or layered with other markings. The other ideas don’t capture the defining difference. The presence or absence of a border isn’t about what unit type the symbol represents, nor is it about color-coded borders or grid coordinates. Those aspects may appear in other aspects of symbol design, but the essential distinction here is the border around the symbol.
