What is the method of creating texture with dots called?

Correct answer: Stippling

Stippling is a mark-making method in which small dots, spots or dabs are placed repeatedly to build texture, tone or colour. Option B is therefore correct. Glazing uses a transparent layer, scumbling uses broken or scrubbed strokes through which an underlying colour may show, and impasto creates raised texture with thick paint. These techniques are distinct from dot-based application.
