What is the benefit of a ground layer before applying acrylic paint on canvas?

Correct answer: It makes the surface even and receptive to paint

The governing concept is surface preparation. A suitable ground, such as an appropriate priming layer, helps even out the canvas texture and regulates how readily it absorbs paint. This gives acrylic colour a more predictable surface and supports smoother, more uniform application. Therefore, option B is correct. A ground does not always make paint transparent, harden the brush, or bend paper. The exact result depends on the ground used and the prepared support.
