Which selection tool would be the best choice for an irregularly shaped object?

The Lasso Tool is the best choice for selecting an irregularly shaped object due to its freeform selection capability. This tool allows you to draw around the edges of the object manually, which is particularly useful for capturing complex shapes that do not conform to standard geometric forms.

While the Rectangle and Elliptical Marquee Tools are designed for selecting rectangular and elliptical areas, respectively, they lack the flexibility needed for irregular shapes. The Magic Wand Tool can select areas based on color similarity but may struggle with complex shapes that have varying colors or textures, leading to incomplete or imprecise selections. In contrast, the Lasso Tool empowers users to outline the object exactly how they want, making it ideal for detailed work.
