Which command allows you to change the stroke width of an object in Illustrator?

The command that effectively allows you to change the stroke width of an object in Illustrator is found within the Properties panel. This panel provides a straightforward and convenient way to adjust various attributes of selected objects, including the stroke width. When you select an object and navigate to the Stroke section within the Properties panel, you can easily input a new width value or use the slider to adjust it in real time.

The Properties panel is context-sensitive, displaying relevant options for the selected object, which streamlines the design process. By using this option, you can maintain a more integrated workflow without needing to navigate through multiple menus.

The other choices, while they may seem plausible, do not accurately represent how to change the stroke width in the most efficient manner. Understanding the functionality of each option clarifies why the Properties panel is the optimal choice for this task.
