TaskBoard application access, Browse projects project permission, Schedule issues project permission, and Edit issues project permission are the correct options.

TaskBoard application access is required so the user can open and use the TaskBoard Cloud interface where backlog ordering is performed. If a user cannot access the application they cannot move items inside that app.

Browse projects project permission is required so the user can view the project and its backlog. Without browse rights the backlog and the issues in it are not visible and the user cannot reorder items.

Schedule issues project permission allows the user to change scheduling fields that some boards or backlog views use when repositioning or managing issue order. This permission often underpins reordering actions that adjust planned dates or releases.

Edit issues project permission is required so the user can modify the issue fields that the board uses to reflect position or status. Reordering usually makes changes to issue fields so edit rights are necessary.

Create issues project permission is incorrect because creating new issues is not required to move existing items within the backlog.

Manage sprints project permission is incorrect because managing sprint settings or starting and closing sprints is different from reordering backlog items.

Manage boards project permission is incorrect because changing board configuration is not required for a user to move issues within an existing backlog view.

Rank issues global permission is incorrect in this scenario because the TaskBoard Cloud workflow requires application access along with project level browse, schedule, and edit rights instead of that global permission.
