If a dry-brush stroke forms a solid band instead of the expected texture, then what is the reason?

Correct answer: The brush contains too much paint or moisture

Dry-brush texture depends on removing most paint and moisture before dragging the bristles across the surface. The remaining small amount catches only parts of the texture and leaves broken marks. If the brush carries too much paint or moisture, it fills the gaps between bristles and produces a solid band. Thus option B is correct; brush size, a rough surface and light pressure do not explain this result as directly.
