Final answer:
The correct way to change the layer color to Gold in Adobe Illustrator is through the 'Layer > Change Layer Color' option, not found in the Window, Object, or Edit menus.
Step-by-step explanation:
To change the layer color of the graphics layer to Gold to improve the visibility of selected objects in Adobe Illustrator, the correct pathway is Layer > Change Layer Color. This option is not found under the Window, Object, or Edit menus. To use this feature, click on the 'Layers' Panel (usually on the right-hand side), find the layer you want to change, double-click it, and then choose 'Options for [Layer Name]'. In the dialog box that appears, you can change the color by selecting Gold from the dropdown menu next to the 'Color' option.
