Which command allows you to resize an active selection in Photoshop?

The Free Transform command is the correct choice for resizing an active selection in Photoshop. This command provides a versatile way to adjust the size, rotate, and even skew a selection or layer. Once you initiate Free Transform, handles appear around the selection, allowing you to click and drag these handles to scale your selection proportionally or non-proportionally, depending on how you manipulate the handles.

This command also supports other transformations, such as rotating and warping, making it a powerful tool for detailed adjustments. It can be accessed through the Edit menu or by using the keyboard shortcut, which enhances workflow efficiency.

The other choices do not provide the same comprehensive features for resizing an active selection. While Layer Transform may suggest the ability to alter layers, it does not specifically refer to selections. The Scale Selection option isn't a standard command in Photoshop, possibly causing confusion. The Resize Tool does not exist in Photoshop terminology, as resizing is typically conducted through transformation commands. Thus, Free Transform stands out as the best option for resizing an active selection.
