What tool is utilized in graphics programs to select a free-hand area of either a layer or the canvas?

The lasso tool is utilized in graphics programs to select a free-hand area of either a layer or the canvas. This tool allows users to draw arbitrary shapes around the desired selection, making it ideal for selecting free-form areas that do not conform to standard geometric shapes. The lasso tool provides flexibility and precision, which is particularly useful for selecting complex objects or intricate details within an image, such as a person's silhouette or an irregular shape.

In contrast, the rectangle and marquee options are designed for selecting rectangular or geometric areas and do not offer the same level of control for freehand selection. The pen tool is primarily used for drawing and creating paths rather than making selections, which makes it less suited for this specific function. Thus, the lasso tool is the best choice for selecting free-hand areas in graphic design applications.
