The correct option is Send notifications to the chosen component lead.

Company managed projects provide the traditional components feature and the associated component lead field. This allows notifications and automation to be targeted to the component lead as part of project configuration and project level workflows. That capability relies on the components model that is only present in company managed projects.

Show subtasks grouped on the project board is incorrect because grouping and board card layout are board configuration options. Boards in both project types can be configured to show subtasks or parent relationships and this is not exclusive to company managed projects.

Add the issue navigator to the project sidebar is incorrect because the issue navigator is a global Jira interface and links or shortcuts to it can be added without requiring the company managed components model.

Turn on a backlog for a Kanban board is incorrect because backlog support for Kanban boards is a board feature and can be enabled in board settings for the appropriate project types. It is not a capability that only company managed projects can provide.

Change the color assigned to an epic is incorrect because epic coloring and card appearance are board and issue presentation settings. Those visual settings are managed at the board or project level and are not restricted to company managed projects.
