When applying paint with a brush, which of the following pairs of techniques are recommended?

Correct Answer: Option D — Brushes should be dipped into the paint to cover only the ends of the bristles, and the paint should be applied in parallel strokes only.

Dipping only the ends of the bristles prevents overloading the brush, which causes drips and uneven coats. Applying paint in parallel strokes ensures a uniform film thickness and a professional finish, whereas cross-stroking can lead to brush marks and inconsistent coverage on the surface being painted.
