The correct options are Sub-filters exist only on company-managed boards and A board sub-filter query changes the issues shown on a Kanban board and its backlog.

Sub-filters exist only on company-managed boards means that sub-filters are a configuration feature of classic company-managed boards and are not available in the simplified team-managed board settings. In company-managed boards you can add a sub-filter to refine what the board and backlog display without changing the main board filter.

A board sub-filter query changes the issues shown on a Kanban board and its backlog explains that a board sub-filter is applied in addition to the board filter so it narrows the issues that appear on the Kanban board and in the backlog. The sub-filter affects what is visible on those board views rather than modifying the underlying project data.

Sub-filters are available on both company-managed and team-managed boards is incorrect because sub-filters are implemented only for company-managed boards and the team-managed project model does not include that board-level feature.

Only Jira administrators can create sub-filters for any board is incorrect because creating or editing a sub-filter is done by users with the appropriate board or project administration permissions and it is not restricted solely to Jira system administrators.

A sub-filter will alter the Kanban board, the backlog, and the board reports is incorrect because a sub-filter changes the board and backlog views but it does not automatically change the standard board reports which often rely on the board filter or stored historical data rather than the active sub-filter.
