What is the most likely reason if a new acrylic layer repeatedly slips over a dry layer?

Answer and explanation

Correct answer: The surface is overly smooth or greasy

The governing concept is surface preparation and adhesion. A new acrylic layer must grip the underlying film; grease, wax, dust, or an excessively slick surface prevents proper contact, so the fresh paint beads, slides, or lifts instead of settling. Option D identifies the most likely cause. A light lower layer, pure colour, or pointed brush does not normally prevent adhesion. Cleaning and suitably preparing the surface improves the bond.
