What problem may occur if the top of a thick acrylic layer dries while the inside remains soft?

Answer and explanation

Correct answer: The layer may shrink crack or deform under pressure

The governing concept is uneven drying in a thick acrylic layer. Acrylic dries from the exposed surface inward, so the top may form a skin while the material below remains soft. As the interior loses moisture, the layer can shrink unevenly, producing cracks, wrinkles, or deformation when touched. Options A, B, and C do not describe the physical effect of internal softness. Applying thinner layers and allowing adequate drying time reduces this risk, so option D is correct.
