Which sign may be visible while observing a rough surface?

Answer and explanation

Correct answer: Irregular small marks

A rough surface commonly appears grainy or uneven and may be represented by irregular small marks, broken strokes, varied dots, or uneven tonal patches. Therefore, option C is correct. An even, smooth tone more often suggests a polished surface, transparency is unrelated to roughness, and the absence of edges does not identify surface texture. The marks should follow the form rather than be placed randomly.
