    Answer : Option C

    Explanation :

    If a paint is applied excessively thick then wrinkling occurs. Grinning occurs when under coat and final coat are of different colours. Running occurs if the surface is too smooth; paint run off from such parts. Flaking occurs due to poor adhesion, leading to peeling off of paint.
