The correct options are Create multiple issues at once and A project administrator can define custom issue types for the project.

Team-managed projects expose a simple, per-project interface that lets the team add many items quickly, which is why Create multiple issues at once is exclusive to team-managed projects. This capability is part of the self-contained project experience and does not rely on shared administration across the site.

Team-managed projects are designed so the project admin controls project-level configuration, which is why A project administrator can define custom issue types for the project is correct. In team-managed projects issue types are created and managed inside the project by the project admin rather than by global schemes.

Apply issue-level restrictions so only selected project roles can view issues is wrong because issue security schemes and fine grained issue level restrictions are handled in company-managed projects and require global or site level configuration rather than the per-project controls used by team-managed projects.

Use a shared workflow scheme across several projects is wrong because team-managed projects do not support shared workflow schemes. Workflows in team-managed projects are configured per project and they are not managed through shared schemes that span multiple projects.

Adjust the set of issue types available in the project is wrong as an exclusive behavior because both project types can have their available issue types changed, and company-managed projects achieve this through shared issue type schemes. The ability to change which issue types are available is not unique to team-managed projects.
