Which menu allows you to open any panel and manage your workspaces?

The correct choice, which is the Window menu, provides access to all the panels in Adobe After Effects, allowing users to open or close them as necessary to optimize their workspace. This menu is essential for managing the different aspects of the software, such as the timeline, effects, and project panels.

Through the Window menu, you can not only show or hide various panels but also create and save custom workspaces tailored to your workflow. Customizing workspaces helps streamline the editing process and allows users to have all necessary tools at their fingertips.

In contrast, the other menus serve different purposes. The File menu is primarily focused on file management tasks, such as opening, saving, and exporting projects. The Help menu provides access to documentation and resources for troubleshooting or learning more about the software. The Composition menu is specific to actions related to compositions, such as creating new compositions or modifying settings. Each of these menus plays a distinct role, but none offer the comprehensive panel management and workspace customization that the Window menu does.
