What is a common characteristic of 'striated' objects?

Striated objects are specifically characterized by their distinct stripes or ridges, which are often visible on their surfaces. This striation can occur in various natural forms, such as certain minerals and rocks, as well as in biological entities like muscle tissue. The presence of these stripes or ridges typically results from the way these objects are formed or structured, making option D the most accurate representation of a common characteristic of striated objects.

While solid and rough surfaces may describe some striated objects, they do not capture the exclusive essence of what makes them striated. Smooth surfaces do not apply as a defining feature of striated objects, as striations inherently create some form of texture or variation on the surface. Therefore, the defining characteristic is the striped or ridged appearance prevalent in these objects.
