What feature can be used to create a path based on an object's outline?

The Pen tool is ideal for creating paths based on an object's outline because it allows for precision and control when tracing around shapes and objects. With the Pen tool, you can create smooth, scalable vector paths that can be manipulated with anchor points and handles. This flexibility makes it an essential tool for tasks such as creating complex selections or shapes that require detailed outlining.

In contrast, the Magic Wand tool is designed for selecting areas of similar color, making it less suitable for outlining an object accurately. The Lasso tool provides a freehand selection method but lacks the precision and control necessary for creating defined paths. Meanwhile, the Brush tool is primarily used for painting and applying strokes of color rather than selecting or outlining objects. Therefore, the Pen tool stands out as the most appropriate choice for creating paths based on an object's outline.
