The correct options are The background colour of the primary navigation bar and The colour of the create issue button and the highlight used for the currently selected navigation item.

The global Look and Feel controls the top level branding and the primary accent used across the product interface. That is why The background colour of the primary navigation bar is correct because the header or navigation bar is part of the global branding that these settings change.

The same global accent is applied to prominent actions and selection highlights which is why The colour of the create issue button and the highlight used for the currently selected navigation item is correct. The setting provides a single primary color that is used for the main action button and for highlighting the active navigation item to keep the product appearance consistent.

The background colour of the project sidebar is incorrect because sidebars and per project panels are part of the content layout and are not typically overridden by the global Look and Feel branding.

The colour palette applied to every button across the application is incorrect because the global setting usually sets a single primary accent for key actions and highlights and it does not recolour every button variant and contextual control across the product.

The background colour of the issue detail view is incorrect because the issue content area background remains the page or theme default and is not replaced by the global look and feel accent settings.
