What is the technique of creating a dotted texture called?

Correct answer: Stippling

The governing concept is mark-making for texture. Stippling creates a surface effect by placing many separate dots or small touches, often with the tip of a brush or another tool. Thus option A is correct. Blending produces a gradual transition, wash lays down a fluid transparent area, and dry brush usually creates broken, rough marks rather than a specifically dotted pattern.
