The correct options are Quick filters are available on both Scrum and Kanban boards, Estimations can only be recorded while issues are in the backlog and only on Scrum boards, Kanban boards are the only board type that can hide completed issues from the active board view and Both Scrum and Kanban boards are ordered by rank by default.

Quick filters are available on both Scrum and Kanban boards because quick filters act at the board view level and let users temporarily narrow which issues are visible without changing the underlying board query. That makes them useful on either board type for focusing on specific issue attributes or workflow states.

Estimations can only be recorded while issues are in the backlog and only on Scrum boards means that estimate values are entered during backlog refinement or sprint planning and are not captured on the active Kanban board. Scrum workflows rely on backlog estimates for sprint planning while Kanban emphasizes flow and work in progress rather than backlog-based estimation.

Kanban boards are the only board type that can hide completed issues from the active board view because Kanban focuses on continuous flow and keeping the active board uncluttered. Hiding completed issues helps teams maintain visibility on work in progress while completed work is not shown on the active Kanban board. Scrum boards typically retain completed items within the sprint until the sprint is completed.

Both Scrum and Kanban boards are ordered by rank by default since rank determines the relative ordering of issues on the backlog or within columns and is the default sorting method on both board types. Users can reorder items manually which updates the rank used by the board.

Both Scrum and Kanban boards can apply sub filters to the board query is incorrect because sub filters are not available on both board types. Sub filter capabilities are limited to specific board configurations and are not applied to Scrum boards in the same way they are on Kanban boards in Sprintwise.
