What is suitable if bubbles appear in a wet poster-colour layer?

Answer and explanation

Correct answer: Carefully break them and apply a light even stroke

The governing concept is gentle surface correction while the paint remains workable. A visible bubble can be carefully released, after which a light, even stroke levels the wet layer. Hence option B is correct. Adding a large amount of paint may make the patch thick, scraping the whole surface is unnecessarily destructive, and folding wet paper can create creases or damage the design. Controlled strokes are safer.
