Which of the following components is used to manage workspaces in Premiere?

The correct choice for managing workspaces in Adobe Premiere is the Window menu. This menu provides access to various workspace options that allow users to customize their editing environment based on their needs. Within the Window menu, you can select different workspaces like Assembly, Editing, Color, and More, or reset to saved layouts.

This functionality is crucial for efficiently navigating the software, as it enables users to prioritize different tools and panels depending on the task at hand, such as video editing, color grading, or audio mixing. The other menus, while important for various functions in the software, do not contain the workspace management features found specifically in the Window menu. Thus, understanding the role of the Window menu is essential for optimizing your workflow in Premiere.
