Which of the following can be used to view selected components in a separate window tab?

The option "Isolate in New Window" is correct because this feature specifically allows users to isolate selected components from the main assembly and displays them in a separate window. This enables designers to focus on particular parts without distractions from the rest of the assembly.

This functionality is particularly useful for detailed analysis, modification, or presentations of specific components without losing the context of the overall design. It streamlines the workflow by reducing clutter and allowing users to concentrate on individual elements effectively.

The other options either do not relate directly to isolating components in a separate window or are not standard features in NX. For instance, "Open in New Tab" might imply viewing in a different panel, but it doesn't specifically isolate components. "View Separate Component" sounds plausible but lacks direct mention of isolation or separation in a user-defined context. "Detach from Assembly" suggests modifying the component’s relationship to the assembly rather than viewing it separately, which changes the assembly structure rather than providing a focused view.
