What may happen if acrylic colour is left exposed on a palette for a long time?

Answer and explanation

Correct answer: The paint may dry and harden

Acrylic colour contains a water-based binder that loses moisture when the paint is exposed to air. With continued exposure, the paint changes from a workable fluid into a dry, hard film and may no longer spread smoothly. Therefore option D is correct. It does not become wetter or turn into oil, and leaving paint exposed cannot physically enlarge the palette. Keeping the lid closed or using small portions helps prevent waste.
